Introducing 3.5-meter ZiYuan-3 (ZY-3) Stereo Imagery

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. ZY-3 stereo is an ideal solution for you as it has both large footprints and extensive archive dating back to 2012 with near global coverage. ZY-3 provides 3.5-meter (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 sales@apollomapping.com and we would be happy to locate coverage and price out the data.

  • Mono Sensor Resolution:1-m panchromatic & 5.8-m multispectral (blue, green, red and near-infrared [NIR]), at-nadir
