Global Geodata Availability & County Catalog
Coverage varies by product type. Below is a summary of our geodata solutions starting with low cost global data options and finishing with larger-scale (more detailed) mapping solutions,
you may also navigate the listings below for availability by country;
please contact us for nautical chart/bathymetry data availability.
Low-cost global data options include:
SRTM30 – the earlier GTOPO30 30 arc second (approx. 1km) resolution worldwide DEM (Digital Elevation Model) dataset enhanced with reduced resolution SRTM (Shuttle Radar Topography Mission) where available
GDEM – 1 arc second DEM made from ASTER stereo pairs (higher resolution than SRTM3 but lower accuracy and numerous anomalies)
SRTM3 - Shuttle Radar Topography Mission 3 arc second (aprox. 90m) resolution DEMs. This is the lowest-cost option for DEMs of this level of detail and accuracy, however there are void regions (gaps / holes of missing data, especially prevalent in areas of high relief) -- these can be interpolated and/or "seeded" with terrain values from other sources however will then have lower accuracy. In addition, the SRTM dataset does not include land areas above 60º north or below 56° south latitude.
Circa 1990 30m resolution Landsat 5 and circa 2000 15m resolution Landsat 7 satellite imagery as 7-4-2 false color composites or simulated natural color (additional Landsat imagery including the new Landsat 8 can be downloaded for free on a per scene basis; LAND INFO can custom process to your specifications for instance pan-sharpened ortho mosaics)
WVS+ -- World Vector Shoreline Plus 1:250,000 vector data of the World's coastlines and international boundaries
V-MAP 0 -- US military 1:1,000,000 vector mapping
ONC -- US military 1:1,000,000 Operational Navigation Chart raster mapping (GeoTiff DRGs -- Digital Raster Graphics)
JNC -- US military 1:2,000,000 Jet Navigation Chart raster mapping (GeoTiff DRGs)
Regional data products include options such as:
1:500,000 US military TPC (Tactical Pilotage Chart) and/or 1:250,000 JOG (Joint Operations Graphic) topographic maps – as DRGs (Digital Raster Graphics) these are low cost, pricing is higher for other formats.
LAND INFO off-shelf 250m land-use/land-cover
Country data options generally include 1:50,000 – 1:250,000 digital topographic map data. For some regions, 1:25,000 scale mapping is also available. Please select links below for data availability for individual countries, or contact us to request our complete global Geodata catalog, which includes all of the countries in a single file. Topographic maps are generally produced by national mapping agencies or the Russian (Soviet) military, or the US military. US military maps are made by NGA (National Geospatial-Intelligence Agency, established 2003), sometimes in conjunction with US allies/partner countries. NGA was formerly known as NIMA (National Imagery and Mapping Agency, 1996 – 2003) and before that was called the Defense Mapping Agency (DMA 1972 – 1996). There are also some maps from the Army Map Service (AMS) still in circulation. Please note that due to copyright restrictions some topographic maps are only available in their original paper format.
Digital topographic map data can be delivered as DRGs, DEMs and/or vector layers such as contours, hydrology and transportation/roads. For areas where suitable topographic maps aren't available, medium-resolution satellite imagery such as RapidEye, SPOTMAPs and SPOT-6 is affordable for large-area coverage, and much more up-to-date than topographic maps. Where higher-resolution/accuracy terrain data is required, DEMs can be generated from a variety of additional sources.
Please note that DEMs from optical stereo pairs are contingent upon cloud-free stereo pair imagery availability and are therefore not well-suited for tropical areas -- please contact us for our free report on DEMs from High-Res Optical Satellite Stereo Pairs.
City / large-scale (detailed) mapping (generally 1:10,000 - 1:25,000) is available for over 1,800 cities worldwide from Russian military mapping sources --

High-resolution satellite imagery (worldwide availability)
High-resolution satellite imagery such as IKONOS 1m, QuickBird 60cm, WorldView-1 50cm (pan only), GeoEye-1 50cm, WorldView-2 50cm and Pléiades 50cm is typically the most detailed, up-to-date and accurate data source without having to arrange for a aerial flight or ground survey. Sold by sq. km., high-resolution satellite imagery is suitable for covering cities and project-specific areas..
Land Info can enhance the value of your imagery via:
- Image processing services such as ortho-rectification, tonal balancing, mosaic output, dataset blending, pan-sharpening, band manipulation, 16 to 8-bit scaling/DRA (Dynamic Range Adjustment), cloud-patching, atmospheric correction, wavelet compression, GPS GCP (Ground Control Point) target location and accuracy assessment
- Vector feature extraction (buildings, roads, hydrology), classification services (land-use, land-cover, vegetation, impervious surface mapping and change detection) via traditional spectral-based methods and Object Based Image Analysis
- Terrain services including auto-correlation, photogrammetry, radargrammetry, bare-earth editing, contour generation and 3d urban building model creation
All data is delivered in industry standard file formats such as GeoTiff, NITF, ER Mapper .ecw, LizardTech MrSID .sid, JPG2000 .jp2, Idrisi .rst, ERDAS .img, ESRI .shp shapefile or .mdb GeoDatabase, AutoCAD .dxf or .dwg, MicroStation .dgn, MapInfo MIF/MID/TAB, USGS ASCII .dem, ARC ASCII GRID, DTED and .bil (other formats available upon request). All data includes customer choice of projection.
Land Info is a GeoEye Authorized Reseller, DigitalGlobe Distribution Partner, Astrium GEO-Information Services SPOT Image Partner, RapidEye Direct Distributor, Authorized Intermap Data Distributor, USGS Business Partner and Esri Business Partner.
For data selection assistance, please contact us with your area of interest (ESRI .shp or Google Earth .kmz vector polygons preferred) and a description of your project.
