Availability of ASCII to raster and boundary cleaning methods in geotrellis #2321

Open SrinivasRIL opened 7 years ago

SrinivasRIL commented 7 years ago

Hi,

I am pretty new to spark and geotrellis. We are using ESRI ArcGIS to deal with raster data. Currently we have developed a model which smoothens boundary based on majority filter and boundary cleaning tool available in the ESRI spatial analyst toolbox. However we are taking an ASCII file generated by a tool and using it as an input, convert it into a raster and then follow the tools as mentioned above. However since we are talking about a huge dataset it takes a lot of time to generate the desired output, so we are talking about spark and geotrellis. I have been looking through geotrellis and I wanted to know if there are similar packages/modules available in Geotrellis where we can use ascii file as an input, convert it into a raster, reclassify and then smoothen the edges? I am also open for an alternate approach as well?

Thank you, awaiting a response.

@SrinivasRIL Can you provide an example of what you mean by "ASCII file"?
