Tech Maven Geospatial has data ready for your offline mapping project!
SQLite Databases with Raster, Vector and Terrain/Elevation Tiles (in both MBTiles and GeoPackage formats)
We can also translate these formats into other widely used formats to meet whatever specific need you have and to accommodate your mapping platform. See List
We can develop custom offline maps to suit any needs
We have the bandwidth and CPU’s to handle processing satellite imagery to zoom level 24 and large scales
Raster Tiling
Specialized Raster Tiling Services
Image Optimization – Providing the best compromise for file size and quality
Composing multiple tile layers together
Changing Colors, Adjusting Transparency/Opacity
Vector Tiles
MapBox Vector Tiles (GZipped PBF Protocol Buffers) in TMS schema in mbtiles or can be folder of XYZ or TMS tiles.
We have specialized tools for building vector tiles from databases and Vector GIS Data.
Elevation/Terrain Tiles
We have worldwide elevation data from multiple sources and processed into 256×256 tiles following the TMS Schema.
There are several formats we can deliver.
- PNG with RGB values with a formula representing height/elevation
- Cesium Terrain Formats – Quantized Mesh and Grid Formats
- GeoPackage Elevation
extracts/downloads from Publicly available Tile Servers, Map Servers
Build custom offline maps from your existing GIS Data or Raster Imagery

MBTILES SQLite
MBTILES is probably the best format with vector tiles and raster tiles. GeoPackage is good with it’s Vector Features (similar to WKB geom column) and flexible projections for raster tiles.
Data Products
We have many data products staged and ready to go.
We can also cut an area of interest (clip) the data and also reduce the number of zoom levels as needed to keep file size down.
