Perhaps if you are new to code but familiar with GIS software this will seem slightly odd. If you just want to delineate non-vegetation objects and don’t want to use machine learning, you can do that by using the raster to vector conversion function and NDVI values. Once uploaded you can import it into your GEE project/map by clicking on the arrow associated with it in your Asset tab.

If anyone has current or past projects that they are willing to share, please feel free to do so. 1.

As I got to know my way around Earth Engine, I started compiling a mental list of tips for addressing challenges like avoiding computational limits in classification, and shared my tips on Twitter. It still seems to be that way. Below, I highlight recent forest fires in Queensland and New South Wales, Australia by comparing high-vegetation area images. Next, add the Sentinel 5P dataset and filter on the NO2 column number density and a date range.

Sentinel 5P dataset and filter on the NO2 column number density. Based on the script, I hoped I could apply this technique to highlight areas or pixels of interest, such as a deforestation area. One of the things that is great about GEE is its ability to handle deep time series and we now have a decent amount of data from Sentinel 5P. // Export the FeatureCollection to a SHP file.

Harel Dan, a GIS coordinator at 4M Analytics in Israel, took the idea a step further by writing a script for the Sentinel Hub platform. You can use this example in Code Editor to get you started.

It is worth knowing this, if you don’t get the result you were expecting.

The grey background was used to mask low-vegetation areas, so the colors only show where there were dense trees in May 2019.

Geographic Information Systems Stack Exchange is a question and answer site for cartographers, geographers and GIS professionals. Why is violin tuning order the way it is?
