Note that the layer created by tool is temporary and will not persist after your ArcMap session ends unless you save the document.įormerly a Mapping Center Ask a Cartographer Q & A. The tool allows you to use an expression to create a subset of the data. The My Esri self-service portal is your one-stop destination to access Esri products and services, review your orders, get resources, and more. With this, you can achieve the same result as with a definition query. Is this even workable aim for ModelBuilder? Am I trying to go about it the wrong way?Īnswer: You can use the Make Feature Layer tool available in the Layers and Table Views toolset of the Data Management Toolbox. ![]() Since I’m so used to working in this manner I thought I’d be able to achieve the same thing in ModelBuilder but this appears not to be the case.Īs I didn’t even know if this was workable I thought I’d “Ask a Cartographer”. While there is a limit to the number of features included in the. In the past, if I only wanted to work with areas that had access, I was able to set the coverage’s Definition Query to = “Y”. The query operation queries a feature service resource and returns either a feature set for each layer in the query, a count of features for each layer (if returnCountOnly is set to true ), or an array of feature IDs for each layer in the query (if returnIdsOnly is set to true ). All input feature classes or tables must be from the same input workspace. Make Query Table accepts data from an ArcSDE geodatabase, a personal geodatabase, or an OLE DB connection. The query can be used to join several tables or return a subset of columns or rows from the original data in the database. This coverage layer however has a field in it which defines accessible areas.Īreas that are accessible have a “Y” in the field, those that don’t, are empty. The Make Query Table tool applies an SQL query to a database and the results are represented in a layer or table view. ![]() In my last step of the model, I am trying to “Clip (analysis)” my polygon (produced by the Raster to Polygon tool) based on a coverage layer. (with data locations highlighted and the standard GIS Identify tool implemented to query data) and as a table that can be output as a shapefile or. Ultimately it will convert the raster to a polygon where I may use it in my maps. Question: I’m currently finishing up a model which performs many different operations on a single raster.
