Are you in need of stereo satellite imagery but hate having to look through a plethora of hard-to-use search engines in the process? Do you wish you could also search for stereo coverage after already looking at mono imagery results for a given area, without having to leave the search engine you have open?
If these issues sound familiar or you just need a wider array of archived stereo data, then ZY-3 stereo imagery is the solution for you!
Apollo Mapping is excited to announce the addition of ZiYuan-3 stereo results to our already diverse collection of satellite imagery options in our online search engine, Image Hunter. Stereo imagery from ZY-3 is an ideal solution for you as it has both large footprints and extensive archive dating back to 2012 with extensive global coverage. ZY-3 is a two satellite constellation of nearly identical sensors providing 2.5-meter (m) and 3.5-m panchromatic optical stereo pairs – as well as 2.1-m panchromatic and 5.8-m multispectral mono imagery.
As an added bonus, we also offer reasonably priced 7-m digital elevation models (DEM) extracted from ZY-3 stereo pairs. Our ZY-3 DEMs are available as both digital surface models (DSM) where surface features such as vegetation and human structures remain visible; and as digital terrain models (DTM) where the surface features found in a DSM have been removed so that elevations represent the bare earth below.
If you would like to find out more about ZY-3 stereo, you can check out our website here; or if you have a specific request for a project you are working on, let us know at [email protected] and we would be happy to locate coverage and price out the data.
