GIS and CAD Services




GIS (geographic information systems) is an area that is always evolving becoming more and more integrated into enterprise IT.By leveraging maps as visualization tools, spatial analytics for predictive modeling, and a geographic platform for sharing and collaboration, you get improved and more insightful answers to your business questions. How spatially mature is your business? Maybe your enterprise systems are leaving you geographically blind and you want to become more location-aware. Perhaps your day-to-day decisions need to be more influenced by location analytics. Or, perhaps the very well-being of your business is highly dependent on being in the right place at the right time and you need location technology completely entrenched across your organization.

Business Analysis and Mapping:


A key function of geographic business analysis involves determining the optimum site location for retail outlets, manufacturing plants, distribution centers, and administrative offices. Attribute selection algorithms and raster/vector algebra is used to identify locations that meet a range of selection criteria such as zoning and land use; population demographics; household income; education; proximity to transportation features such as highways, railways, ports, and air; commuting distance and availability of recreational features. Business analysis can also be used to find the location of competitors, suppliers, and current and potential customers. Geographic business analysis also uses demographics such as household income, age-based population breakdown, and home and car ownership combined with zip code spending patterns to target geographic product preferences and marketing campaign strategies. When combined with geocoding, zip code spending patterns can be used to prepare address lists for mail and advertising campaigns

Transportation Mapping:


Transportation mapping and analysis ranges from the basic preparation of reference maps showing the location and hierarchy of roads, rail lines, airports, and pipelines to complex maps combining reference and thematic maps that illustrate such parameters as traffic patterns, time dependent volume and system capacity, and network optimization including the location of distribution centers and route optimization. Services AJD Geospatial Concepts provide include:

  • Preparing reference maps of road networks showing the location of roads and associated stoplights, signs, crosswalks, and turning lanes along with limited access routes and their entrances and exits.
  • Preparing reference maps of road networks showing the location of roads and associated stoplights, signs, crosswalks, and turning lanes along with limited access routes and their entrances and exits.
  • Preparing reference maps of road networks showing the location of roads and associated stoplights, signs, crosswalks, and turning lanes along with limited access routes and their entrances and exits.
  • Preparing combined thematic maps analyzing the source, destination, and volume of customers for transit/bus routes
  • Creating a distribution network and channel
  • Preparing thematic maps analyzing accident rates, traffic patterns, and time-dependent system capacity and volume
  • Preparing thematic maps analyzing accident rates, traffic patterns, and time-dependent system capacity and volume

3D Mapping:


3D modeling and mapping involves converting LiDAR data or 2D shapefiles that have known vertical elevations associated with the 2D coordinates to three dimensional digital terrain and digital elevation models (DTM and DEM) along with terrain irregular networks (TIN). This modeling and the analyses that can be performed with them are used for a wide range of applications which AJD Geospatial Concepts can undertake including

  • Topographical analysis and site planning for land acquisition and development.
  • Flood inundation mapping and analysis for emergency management, land development, and insurance planning.
  • Park, recreation, facility, and trail site locations.
  • Corridor mapping for power lines, pipelines, roadways, and railways.
  • Building footprint, height, and line-of-sight modeling analysis.
  • Mapping and modeling historical development of cities and towns by combining 3D data with historical data for an area

LiDAR and three-dimensional data are available through State and Federal databases

Infrastructure Mapping:


Community infrastructure includes the electric power grid, telephone/communication networks, water and sewer systems, and neighborhood infrastructure such as sidewalks, roads, and parks. In infrastructure mapping, the services offered involve establishing accurate coordinate locations of point features of a network such as electric transfer stations and towers and the lines that connect them in a power grid and creating databases and shapefiles from which reference maps and lookup tables can be produced. Such databases and reference maps are typically produced for:

  • Electric power grids showing the location of transfer stations, power towers and poles, transmission lines and property boxes.
  • Telephone and communication networks showing the location of cell phone and communication towers; telephone poles; and cable, telephone, and internet lines.
  • Water and Sewer Systems showing the location of pumping stations, manholes, street drains, water and sewer lines, transfer points, and treatment plants.
  • Pedestrian networks showing the location of sidewalks, bike trails, traffic lights, and crosswalks.
  • Natural Gas distribution networks showing the location of pumping stations, shutoff valves, pipelines, and customer points.

After accurate geospatial databases such as these are created ,they can be combined with attribute data on the capacity, size, age, condition, service frequency, etc. of the infrastructure system to produce combined reference and color coded maps that can be used to analyze the system and schedule maintenance, plan and prioritize projects, and seek easements and clearances. Projects where both capacity and condition need to be understood and mapped by segment of the infrastructure network are commonly produced.
