How to use MaxEnt .asc file in ArcPro to perform hotspot analysis?

05 February 2023 1 7K Report

Hello, I have created a roadkill prediction model using MaxEnt and have inputted the .asc output into ArcPro. I would now like to perform further analysis using ArcPro 'Optimized hot spot analysis' tool. I have seen this can be done in multiple scientific papers.

I have tried to convert my .asc file into points using 'Raster to points' tool. Unfortunately, this did not work.

Does anyone know a way to transform the .asc file into point data or perform hot spot analysis on an .asc file without transformation.

Thank you for your time!

MaxEnt .asc files can be used in ArcGIS Pro to perform hotspot analysis, identifying areas of the high occurrence of species or other phenomena of interest. Here are the steps to perform a hotspot analysis using a MaxEnt .asc file in ArcGIS Pro:

Add the MaxEnt .asc file to the ArcGIS Pro map as a raster layer.

Use the Raster to Point tool in the Spatial Analyst toolbox to convert the raster layer into a point layer, representing the locations of the species of interest.

Use the Point Density tool in the Spatial Analyst toolbox to calculate the density of points within a specified search radius.

Use the Reclassify tool in the Spatial Analyst toolbox to reclassify the density raster into a binary raster, where cells with a high density of points are classified as "hotspots," and cells with low density are classified as "non-hotspots."

Use the Raster to Polygon tool in the Conversion toolbox to convert the binary raster into a polygon layer, representing the hotspot areas.

Symbolize the polygon layer to highlight the hotspot areas.

Perform further analysis as needed, such as calculating the area or perimeter of the hotspot polygons or identifying the habitats or land use types within the hotspot areas.
