You can compute cell size based on your input data's extent. Calculate cell size based on your input data's extent Here are a few suggestions for calculating cell size. Creating a raster at too coarse a resolution will result in loss of detail. However, if you create a raster at a higher resolution than what is supported by the source vector data, that raster could be unnecessarily large without adding detail. The advantage to using a single cell size for all rasters is that overlay analysis may be more accurate. One strategy is to make all rasters the same cell size. Therefore, you need to determine a proper cell size. The Feature to Raster tool requires that you enter a cell size for your output raster. The easiest way to convert your vectors to rasters is to use the Feature to Raster tool available in the Weighted Raster Overlay Service toolbox. If you have source vector data you want to use in a weighted overlay, you will need to convert it to a raster geoTIFF format.

Execute the Repair Geometry tool to fix problems found by the Check Geometry tool.

Execute the Check Geometry tool to generate a report of the geometry problems in a feature class.

These tools will prevent striping or bleeding that can occur when a vector layer with certain geometry anomalies is converted to a raster. The following geoprocessing tools should be run on your vector data prior to creating rasters. While this is optional, it will reduce the size of your rasters and could expedite configuration and processing times. If your vector features extend beyond the area of interest you want to use in your weighted overlay service, use the Clip tool to extract features within that area. Mosaic datasets handle projection differences across raster layers. The rasters that will comprise your weighted overlay service will be loaded into a mosaic dataset. All vector data should be rasterized to a common projection.Įxisting raster data does not need to be reprojected unless there is a reason to change pixel size. For example, an equal-area projection may work best for natural resource-related applications because those projections tend to preserve area measurements. This choice will depend on your industry domain. GIS professionals understand that choosing the correct projection is vital to a project's success.

You can download this tool as part of the Weighted Raster Overlay Service toolbox.

This document also references the Feature to Raster tool. This document describes tools and processes that you'll need to understand to successfully prepare your data to participate in a weighted overlay service. Make sure you are familiar with the concepts introduced in that topic before continuing. Use your data in weighted overlay (portal) is an overview of the workflow used to create a weighted overlay service.

Weighted overlay also requires careful consideration and understanding of how to handle gaps or NoData values in your raster datasets. Rasters that participate in a weighted overlay service should be in geoTIFF format. These could include clipping input vectors to an area of interest, projection to a common spatial reference, and validation for potential geometry anomalies. The process of converting vectors to rasters may require several steps. Therefore, if you have vector data that you want to use in a weighted overlay service, you have to convert it to raster datasets. Raster layers are the foundation of a weighted overlay service.
