Geodata Solutions:
Summary, Country Availability & Country 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

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:

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 natur color (additional Landsat imagery is available for free on a per scene basis)

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.

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 on right 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 or higher-resolution/accuracy terrain data is required, the DEMs can be generated from other sources:

• 25m DEMs from ASTER optical stereo pairs (LAND INFO recommends custom-processed ASTER DEMs instead of the off-shelf GDEM product)
• 20m DEMs from SPOT optical stereo pairs
• 10m DEMs from ALOS optical stereo pairs
• 10m DEMs from radar satellite stereo pairs
• 5m DEMs from Intermap airborne radar (conterminous US, Western Europe, select additional areas)
• up to 1m DEMs from high-res optical stereo pairs (GeoEye-1, WorldView-1, WorldView-2)

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 -- please click here for a complete list. A more limited selection is available from US NGA -- please click here for a complete list.

High-resolution satellite imagery (worldwide availability)
High-resolution satellite imagery such as Ikonos 1m, QuickBird 60cm, WorldView-1 50cm (pan only), GeoEye-1 50cm and WorldView-2 50cm is typically the most detailed, up-to-date and accurate data source. Sold by sq. km., high-resolution satellite imagery is suitable for covering cities and project-specific areas (for urban area coverage QuickBird CitySphere ortho mosaics may already be available off-shelf at discounted pricing). Medium-res imagery sold by scene such as ALOS and SPOT Image 2.5m – 10m and RapidEye 5m, along with off-shelf satellite image products such as SPOTMaps 2.5m, are more affordable options to cover large 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) and classification services (land-use, land-cover, vegetation and impervious surface mapping)
• 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.
