Palm Beach County Dept. of Environmental Resources Mgmt.

Applied Technology & Management, Inc. contracted Avineon to provide photogrammetric, photointerpretation and GIS services in support of their Lake Worth Lagoon Seagrass Mapping Project.

Our responsibilities included the preparation of a 2001 GIS coverage of the Lake Worth lagoon seagrasses through fieldwork, photointerpretation of aerial photography, delineation using analytical stereoplotters, and trend analysis to determine gross change in acreage of seagrass beds between previous 1990 and new 2001 maps.

Pre-interpretation fieldwork was completed to verify photographic signatures of seagrass and algae. Avineon developed a Photointerpretation Classification Key to illustrate the representative mapping categories, discuss classification methodology, and provide samples of aerial photographs and photographic prints of the different classification types.

Ground control points (GCP's) were collected from existing one-foot resolution digital orthophotography for aerotriangulation of aerial photography. Fully Analytical Aerial Triangulation (FAAT) was performed to extend ground control and ensure all interpreted data met USGS National Map Accuracy Standards (NMAS) for 1:24,000 scale maps. The FAAT report was approved by a Florida Professional Land Surveyor and Mapper (PLSM).

Photointerpretation and delineation was performed on analytical stereoplotters by Avineon's experienced seagrass photointerpreters, by using photosignature identification, fieldwork notes, and collateral data to produce an accurate Lake Worth Lagoon seagrass file.

CAD files created on the analytical stereoplotter were converted to Arc/Info for digital data validation and correction, and the final Arc/Info coverages were converted to ArcView shapefile format for delivery.

Acreage statistics exported from 2001 Arc/Info coverage and 1990 Arc/Info data were summarized in Excel spreadsheet format as a change matrix for gross change in seagrass beds between the two time periods.

Avineon is providing complete engineering solutions to Petrofac. This involves creating the Piping and Instrumentation diagrams (P&ID) in Intergraph Plant Design System P&ID.


Potomac Electric Power Company (PEPCO)

The PEPCO project involves digital conversion and systems integration services. Digital conversion services include facility maps for inside / outside plant networks, equipment, facilities, and electric distribution plats. These are brought into CAD and ArcInfo databases and object-oriented data models for integration with customer information systems and outage management systems. Services include database design, training, system maintenance, and applications development. Avineon converted thousands of maps of varying types, scales and densities, covering approximately 300 square miles of distribution area. The project consists of scanning mylar and paper source maps and converting them into complete vectorized spatial database using Microstation and ArcInfo. Avineon met demanding production schedules, at one time delivering over 1,000 maps within a 90-day period under budget.

Avineon also won the PEPCO GIS contract to provide GIS development, production, consulting, and training services in support of a full-scale enterprise GIS solution using ArcFM (ArcInfo 8.1) and ArcView. Avineon is developing a GIS requirements analysis and implementation plan that will allow PEPCO's business units to share data and improve efficiencies throughout the organization. Once implemented, PEPCO's GIS will comprise compatible units inventories, outage management system, customer information system, pole inventories, feeder maps, and other related RDBMS and mapping data. Avineon develops and maintains the Facility Management Maintenance software (FMMS) for linking distribution maps in three counties to associated databases using an ACCESS front-end system integrated with a spatial database. This process is being translated in part to support linkage between the ArcFM geodatabase model to PEPCO's Outage Management System.


Qwest (formerly US West Communications)

Avineon provided landbase development and OSP conversion services for various wire centers located within the 14-state area encompassed in Qwest's STREAM OSP-FM (Strategic Engineering Asset Management/Outside Plant - Facilities Management) project.

Avineon first built a master grid, then scanned/warped landbase documents obtained from outside sources to their proper control locations (in some cases, existing digital data was acquired and modified to Qwest's specifications). The resultant raster data was vectorized according to the project specifications. Throughout the course of the project, as surveyed subdivision updates became available from cities and counties, they were scanned and warped to fit the existing landbase, and specific Qwest features were digitized from the raster images to complete the digital landbase.

Avineon posted approximately10,000 design work prints and converting up to 800,000 additional facilities features to Qwest's OSP-FM Vision* system. This contract also included the conversion of additional design work prints, as required, to ensure Qwest's records are kept up to date. Avineon converted the OSP facilities to digital format by "scrubbing" Qwest's manual source documents, performing data entry functions, and placing the graphic elements on Qwest's digital landbase.

The conversion processes for both landbase and facilities data were performed within the MicroStation environment. Delivery of all converted data was made in the GeoVision Interface (GINA) format for migration into Qwest's Vision* system.

Avineon's additional responsibilities for this project included the management of subcontractors who are converting a portion of the wire centers. Earlier in the project, all converted data passed through Avineon's acceptance procedures prior to delivery to Qwest.

The digital landbase was created by performing "heads-up" digitizing of street curbs and roadway centerlines using USGS DOQQ imagery backdrops in the CADTEL Spatial Base environment. Facilities data conversion involves the capture of outside plant source records for copper, fiber, and coax/CATV communication networks.


Social Security Administration (SSA)

Avineon provided engineering services to the SSA headquarters Office of Facilities Management/Office of Realty Management/Department of Architectural and Engineering Services in the areas of CAD and data management. The work consisted of drawing conversion and management effort for a subset of their more than 1,400 nationwide buildings and offices. The project initially involved the inventory and catalog effort of some 50,000 paper facility drawings and many more related documents, as well as development of a Microsoft Access database to contain this information. Avineon established an on-site conversion facility at SSA's Baltimore, Maryland headquarters campus, providing system administration support, scanning, and conversion of facilities data into AutoCAD format.

The conversion effort involved an on-site survey of the building(s) to be converted, and the necessary update of the design documentation, to render products that reflect an as-built condition. Also, in support of this effort, Avineon developed an agency-wide Computer Aided Design and Drafting (CADD) Standards Manual for SSA, including file naming and layering standards, and a standardized symbol block library. Conversion of paper and raster source drawings was done using AutoCAD.

Avineon also analyzed and documented SSA's workflow processes and procedures and developed a standard drawing maintenance and revision process for their intranet-based drawing management system. Avineon then conducted an in-depth analysis of SSA's business and functional requirements as they pertain to the facilities management process, working closely with the Technical Representatives and through working sessions with the user community, to define the requirements for an enterprise-wide web-based Document Management System (DMS). Avineon developed a DMS data model and specification, assessed and evaluated the various COTS DMS solutions available, and documented the evaluation process and results for SSA's use in their acquisition.


South Florida Water Management District

South Florida Water Management District (SFWMD) contracted Avineon to provide photogrammetric, photointerpretation, image processing and GIS services in support of their STA-6 Wetland Vegetation Mapping Project. The project area encompassed 870 acres of filter marsh in the Everglades Agricultural Area.

The services provided include the production of a vegetation map that clearly illustrates and demarcates the vegetative communities within the STA-6 through fieldwork; photointerpretation of aerial photography; and delineation using analytical stereoplotters. A high-resolution, 3-band digital image rectified to the map data was also provided.

Pre-interpretation fieldwork was completed to verify photographic signatures for the twenty vegetation types specified for the project in the District's classification scheme. GPS control points were collected using differential GPS for aerotriangulation of aerial photography. Fully Analytical Aerial Triangulation (FAAT) was performed to extend ground control and ensure that all interpreted data meets horizontal positional accuracy of +/- 15 feet.

Photointerpretation and delineation were conducted on analytical stereoplotters by Avineon photointerpreters experienced in vegetative species identification using photo-signature identification, fieldwork notes, and collateral data to produce an accurate STA-6 Vegetation map.

CAD files were created on analytical stereoplotters and converted to ArcInfo for digital data validation and correction before final delivery in ArcInfo format. Rectification of high-resolution digital images was completed using ERDAS Imagine image rectification tools. The final output was in TIF format.


Southern California Gas Company

Southern California Gas Company (The Gas Company) chose Avineon to perform the latest phase of the Network Analysis System Automation (NASA) Project. The work consisted of enhancing existing MicroStation data for compliance with the Gas Company's current project specifications, which included comparing the data to hard copy records and converting additional facilities information where required.

Upon receipt of The Gas Company's MicroStation data, Avineon generated plots for comparison to the hard copy sources. Records Technicians reviewed the documents and transcribed missing data from the paper records to the plots, creating a comprehensive source.

Following this records preparation task, Avineon's Graphics Operators updated the MicroStation files using the prepared plot as a reference. First, landbase features missing from the MicroStation files, such as street centerlines and political boundaries, were digitized. The accuracy of street and boundary names was then verified against a third party commercial source provided by The Gas Company. Once the landbase data was verified, similar enhancements were made to the facilities data, such as adding missing features to the MicroStation data and correcting features with errors.

After updating, the MicroStation files were subjected to a quality control inspection utilizing both manual and automated techniques before delivery to The Gas Company.

The project area encompassed 18,700 miles of pipe, 1,877 MicroStation files and over 10,000 hard copy records.


Southwest Florida Water Management District

The Southwest Florida Water Management District (SWFWMD) contracted Avineon to map seagrass habitat from aerial photography and to provide photogrammetric, photointerpretation, and GIS services in support of their SWIM seagrass trend analysis project, which has been ongoing at two- year intervals since the early 1980's.

The project scope entails seagrass mapping of the coastal waters of West Central Florida from Tarpon Springs in the north to Boca Grande Pass in the south including St. Joseph's Sound, Clearwater Harbor, Tampa Bay, Sarasota Bay, Lemon Bay and Charlotte Harbor. Avineon will perform a change analysis for the 2001 map by editing the existing 1999 seagrass polygon data using Analytical Stereoplotters to interpret and delineate changes from the new aerial photography.

Deliverables for the project included: a Pre-interpretation Field Work and Classification Key; GPS Procedures and Survey Work; Triangulation Methodology and Full Aerotriangulation Report; Photointerpretation Utilizing Analytical Stereoplotters; Test and Final ArcInfo Coverages; Accuracy Assessment Sampling Strategy Documents; Accuracy Assessment Reports; Final Report.


St. Johns River Water Management District

The St. Johns River Water Management District (SJRWMD) contracted Avineon to provide GIS services in support of their Land Use/Land Cover (LU/LC) Project. SJRWMD encompasses 19 counties in northeast and east-central Florida (approximately 13,000 square miles). LU/LC data is needed to support many of the District's critical goals, such as land acquisition, land management, water allocation planning, water quality monitoring and environmental quality. The data is used as an integral component of models designed to understand existing conditions, develop and prioritize policy implementation strategies, and review the results and effectiveness of these projects and programs. The objective of this project is to review and revise the District's existing 1995 LU/LC data layer; and create a 2000 LU/LC layer by updating the 1995 layer based on USGS 1999 Digital Orthophoto Quarter Quadrangles (DOQQs). The entire project encompasses 880 USGS DOQQs.

All LU/LC and wetlands mapping is completed through photointerpretation and on-screen digitizing of color-infrared (CIR) DOQQs in ArcInfo 8.02. To aid in the classification and delineation process, Avineon's photointerpreters consult and analyze collateral data sources (such as soils maps, National Wetland Inventory maps, topographic maps, and imagery) and perform fieldwork for verification of data. Photographic signatures from aerial photography are correlated to in-field conditions for accurate interpretation and classification of LU/LC types.

All data is processed through a series of Quality Control measures, including visual inspection to ensure interpretation, classification, and positional accuracy specifications are observed. Digital data validation is completed to verify that all coverages conform to the coverage criteria required for the contract. Fully validated and edgematched quad tiles are delivered to the client in ArcInfo export format for review and acceptance.

We were contracted to perform various tasks including field reconnaissance; GPS ground control surveys; digital orthophoto production, photointerpretation of oyster bar and reef habitat, ArcInfo GIS data migration, and positional and classification accuracy assessment of the resultant data.


Deliverables for the project include Triangulation Methodology and Full Aerotriangulation Report; Photointerpretation Utilizing Analytical Stereoplotters; Final ArcInfo Coverages; Accuracy Assessment Sampling Strategy Documents; Accuracy Assessment Reports; and a Final Report.


U.S. Fish and Wildlife Service

The U.S. Fish and Wildlife Service (USFWS) established the National Wetlands Inventory (NWI) program in 1975 to generate and disseminate scientific information on the location and classification of wetlands and deepwater habitats of the United States. Classification of Wetlands and Deepwater Habitats of the United States by Cowardin et al. (1979) is used by NWI for wetlands definition and classification. Photointerpretation conventions, hydric soils lists and wetlands plants lists are also used to implement the Cowardin classification system. NWI maps serve as a nationally accepted tool for environ-mental and socioeconomic decision making relative to coastal zone environmental research, agricultural impact, development management and protection. NWI maps further serve as a valuable database upon which selected parameters may be registered and compiled.

The operational phase of the project consists of 4 main efforts:

  1. photo-interpretation, wetland map compilation;
  2. digitization;
  3. wetland status, trend analysis; and
  4. GPS survey, photogrammetric wetland mapping.

Aerial Photography: Avineon was tasked to prepare aerial photography for each individual Task Order assigned during the project. Tasks included ordering, cutting, indexing, archiving and preparing aerial photos for individual project areas. For photogrammetric Task Orders, we were responsible for laying out ground control and acquiring differential GPS surveyed ground control points in the field. We were also responsible for archiving and distribution of more than twenty 4-drawer filing cabinets of aerial photography for the USFWS.

Aerotriangulation: We completed wetland mapping on more than 165 military installations. Wetlands were delineated using analytical stereoplotters. We were responsible for acquiring ground control using photo identifiable control points. Subsequent aerotriangulation and quality assurance were also completed for each installation.

Land Use/Cover Mapping: Our environmental photointerpretation staff performed field reconnaissance and wetland identification, photointerpretation and delineation of high-altitude imagery, review of existing wetlands information, map drafting and feature transfer to a USGS quad basemap, quality control and final map production. Additionally, we digitized wetland boundaries and classification attributes to establish a GIS database. Several Task Orders required the use of the Anderson et al. land use/land cover classification system (A Land Use and Land Cover Classification System for Use with Remote Sensor Data,) for describing natural upland areas and land use patterns on NWI maps.

Avineon staff inventoried 85% of the United States and its territories, including the production of over 48,000 1:24,000 scale wetland maps. We prepared numerous other thematic maps of the wetland data for use by the USFWS. We have delivered over 16,000 manually and scan digitized wetland and deepwater habitat maps with a 99% acceptance rate.

Trend Analysis: The trend analysis portion of the project required the selection of over 10,000 four square mile study plots nationwide using a stratified random sampling methodology and GIS techniques. Wetland gains and losses were photointerpreted, digitized and quantified using historical aerial photography, change detection and statistical analysis.

The NWI project is the largest environmental mapping and digital geographic database ever undertaken. Data produced by Avineon personnel are available today via the Internet from the NWI home page and from the wetland layer of the National Spatial Data Infrastructure.
