Our solutions use a wide range of geospatial data, including raster maps, vector mapping and aerial photography. We can also provide customers with the following services:
- Mapping data updates
- Real-time display of data sets
- GPS data conversion
- Spatial data re-projection
- Mapping format conversion
We can provide converters for the following mapping data types:
- ASRP – Arc Standard Raster Product is a military format that conforms to the ISO 8211 standard. Data is divided into geographic data sets as Distribution Rectangles (DRs). ASRP directories contain a general information file (.GEN extension) and one or more ASRP zone distribution rectangle (ZDR) image files (.IMG extension).
- CAD - Computer Aided Design drawings are a digital representation of designs or existing objects. They are typically used in engineering, architecture, surveying, and mapping. Many are legal documents that define real-world objects or a proposed plan. Others are data collection documents used by geographic information systems (GIS). CAD drawings are file-based and a popular format for storing and exchanging vector-based spatial information.
- CIB - Controlled Image Base - greyscale images geo-referenced and corrected for distortion due to topographic relief, similar to digital orthophoto quads. They have similar application as a backdrop for other data or as a simple map. CIB is distributed by National Geospatial-Intelligence Agency (NGA).
- DTED - Digital Terrain Elevation Data, a simple, regularly spaced grid of elevation points. Created by NGA, DTED is based on 1 degree of latitude x 1 degree of longitude extents. Other more detailed Terrain Data is available in different formats from other sources.
- ESRI .shp - A shapefile is a simple, non-topological format for storing the geometric location and attribute information of geographic features. Geographic features in a shapefile can be represented by points, lines, or polygons (areas).
- ESRI .asc - A grid is a raster data storage format native to Esri. There are two types of grids: integer grids, representing discrete data, and floating-point grids, representing continuous data.
- GeoTIFF - A public domain metadata standard enabling a TIFF file to be embedded with geo-referencing information such as map projection, coordinate system, ellipsoids, datum, and anything else necessary to establish the exact spatial reference of the file.
- IMG - Produced using IMAGINE image processing software created by ERDAS. IMAGINE files store continuous and discrete single-band data and multiband data.
- MrSID - A high-quality, high-performance compression methodology which reduces the size of large raster datasets.
- JPEG - Joint Photographic Experts Group is a standard for image compression. JPEG is designed for compressing either full-colour three-band (RGB) or grayscale one-band images. Data can be either 8 or 12-bit. While JPEG compression can make a file very small the original image quality is degraded.
- TIFF - Tagged Image File Format is a standard used in the desktop publishing world to interface with scanning and graphic arts packages. TIFF supports black-and-white, grayscale, pseudo colour, and true colour images, all of which can be stored in a compressed or decompressed format.
- GML - Geography Markup Language is the XML grammar defined by the Open Geospatial Consortium (OGC) to express geographical features. GML serves as a modeling language for geographic systems as well as an open interchange format for geographic transactions on the Internet.
- XML - Extensible Markup Language is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable.
- GZ – Compressed data format, used by, amongst others, Ordnance Survey.
- VMAP - Vector Map (also called Vector Smart Map) is a vector-based collection of Geographic Information System (GIS) data about the Earth at various levels of detail. Level 0 coverage is global at low resolution and available in the public domain. Level 1 coverage is also global, but at medium resolution and only partly available in the public domain.
