NonForest raster which has the values 1 and 0 (1 for NonForest pixels and 0 for Forest pixels). The water raster obtained from rivers and lakes layers (having the value 1). Just I inform you that I tried to combine in a unique raster named Constraints: This method is more accurate and less work. Now buffer the "water" polygons with the "Multiple Ring Buffer" tool and specify the distances you wish. Merge the buffered rivers with the lakes to create a single polygon featureclass (let's call this "water"). Since a river has a surface, you can buffer the rivers with a small value (best to choose half the average river width). Since it is not possible to merge different geometry types into the same featureclass, you should choose a geometry type that best represents both types of data (lakes and rivers). It is easier though to do this in vector format. Water = Con(IsNull(),, )Īfter this you can use the water raster in the Euclidean Distance tool and finish with a reclassify to create the intervals. Next you will have to create a new raster combining the "rivers" and "lakes" rasters using a Con statement that looks something like: Before doing that it maybe wise to add a new field and fill it with the value 1. In case you do this the raster way (Spatial Analyst), you will have to convert the rivers and lakes to rasters (separately). There are different solutions to this problem. but these solutions didn't work.Ĭan you show me which solution is the most appropriate to this study case ? Also I transformed these layers to Raster and I used Euclidean Distance in ArcGIS 10.2. I want to create a new layer of proximity factor to the streams (Rivers and lakes) which varies by intervals from 5 (near the streams) to 1 (the most distant zones). I have two layers : Rivers (as a polyline shapefile) and lakes (as a polygon shapefile).
