How to display ASCII Grid data into javascript map

MokraneLateb — Sat, 01 Sep 2018 10:57:28 GMT

Hello everyone,

I have some ASCII Grid files containing data of incoming rain fall. I would like to display the data on top of an arcgis javascript map. I join a file to this post.

Plus, those files are regulary updated (read overwritten) with updated data.

So, anyone knows how to display that kind of data, and update the map ?

ASCII to Raster—Conversion toolbox | ArcGIS Desktop

rename the *.grd to *.asc to make it easier if you are using pro

Save it into a folder as a *.tif and it is floating point

then do what you want with it.

If this is a java thing, hopefully ther is an equivalent access to a tool, if not covert beforehand

In the JS API there is a taster data source layer for this

back after almost a year.

we finally made it possible with a combination of python and javascript. the python code is run on the server and it updates a map service everytime we receive new data.

the javascript code uses a dynamicmapsrevice layer which has a refreshinterval property.

thanks for your help
