Marziye Posted June 12, 2018 Report Share Posted June 12, 2018 I'm trying to find a good source of NDVI imagery, but I'm struggling to find proper high res imagery for Iran. Does anyone have references to high res imagery (less than 10 meter for 4-6 years ago)? Quote Link to comment Share on other sites More sharing options...

maggis Posted March 12, 2019 Report Share Posted March 12, 2019 You may find such NDVI data via satellite imagery service called LandViewer. This tool has a vast database of satellite imagery that is publicly available and is updated on a regular basis. You may set any Index you need to analyze the area of your needs or create any Index of your own. Besides that there are already ready-made tools for obtaining multispectral indices, flexible processing of data on AOI, elementary clustering, using a raster calculator, visualization of scenes in 3D using digital elevation models, changes in territories based on multi-temporal multispectral analysis, as well as creating ready-made animations of changes in terrain and so much more. Here’s a brief guide to types satellite data that can be found on LandViewer. High resolution satellite imagery: SPOT 6, 7 (up to 1.5 m/pxl) SPOT 5 (up to 2.5 m/pxl) Pléiades 1A, 1B (up to 0.5 m/pxl) KOMPSAT-2 (up to 1 m/pxl) KOMPSAT-3А (up to 0.4 m/pxl) KOMPSAT-3 (up to 0.5 m/pxl) SuperView-1 (up to 0.5 m/pxl) Both optical and radar data is available — with global coverage, and short revisiting period that varies from 2 to 5 days. Low & medium resolution imagery: Landsat 4 - archive 1982-1993 Landsat 5 - archive 1984-2013 Landsat 7 - archive since 1999 MODIS - archive since 2012 Landsat 8 - archive since 2013 Sentinel-1 - archive since 2014 Sentinel-2 - archive since 2015 An example of such imagery can be seen below: https://eos.com/landviewer/?lat=33.39447&lng=52.68974&z=11&side=R&slider-id=LV-TEM4-MTYz-MDM3-MjAx-MzM2-NExH-TjAw&slider-b=Red,Green,Blue&slider-anti&slider-pansharpening&id=LV-TEM4-MTYz-MDM3-MjAx-MzM2-NExH-TjAw&b=NIR,Red&expression=(B5-B4)%2F(B5%2BB4)&anti&pansharpening 1 Quote Link to comment Share on other sites More sharing options...
