The Source layer is the layer whose features are used to determine the selection based on its spatial relationship to the target. In these descriptions, the Target layer is the layer in which features are selected. The following spatial query methods are supported using Select By Location. Use a buffer distance in your search (buffer distances are only used with some selection options).Use selected features in the source layer to identify the features to select.To complete your Select by Location specification, you can optionally specify if you want to.Specify the source layer that will be used to select features from the target layer.See Types of supported spatial queries below for an overview of the selection options. Choose the spatial relationship rule that will be used for selection.Identify the target layer(s) from which features will be selected and check them on ( ).Click the drop-down arrow to see your choices. Choose the type of selection that you want to make.Click Selection > Select By Location to open the Select by Location dialog box.For example, select features from USA Counties that touch the boundary of the features in the layer named "Texas." The dialog box guides you in specifying each selection property.

Note that you select features from a layer (or a set of layers) that have a spatial relationship with features from a source layer. Use the following steps to apply the Select By Location tool. You can use a variety of selection methods to select the point, line, or polygon features in one layer that are near or overlap the features in the same or another layer. For instance, if you want to know how many homes were affected by a recent flood, you could select all the homes that fall within the flood boundary. No wonder I was having so much trouble getting the routes to display where I wanted them.The Select By Location tool lets you select features based on their location relative to features in another layer. Fuck! That would have made everything a heck of a lot easier. So, I think I was able to fix the stop problems but then I discovered that the additional part of the route that I'd inserted had this weird loop in it I couldn't get out no matter how I selected the route (shortest path or click segments) so that it.shit I think I just figured it out! My road network includes local roads for display purposes and when I created the. After 20 more minutes of staring at the screen I figured out that I could use the map editor to manually delete the points in the stop layer.

Then I discover that the stop layer can't be opened with exclusive access so that the attributes can be changed. The bitch of it was when I saved the edits, I hadn't deleted the stop on the second pass which, for some reason, changed the pass count field in the stop layer to zero and created the evil. I was finally able to get most of the route altered by realigning nearly half of it. While adding an entirely new route and deleting an entire existing route went off without a hitch I ran into a shit ton of errors when I tried to extend a portion of a route from a stop in the middle of the route along a perpendicular road and back. The transit route system updates were not nearly as enjoyable! I'm using TransCAD version 5.0 which I've found, in general, to be easier to work with route systems but I ran into some frustrating situations today. The road network edits were simple and straightforward, in fact, they didn't even involve any geography editing, just updating some attributes. Today I was editing both a road and transit network to reflect programmed projects in the Transportation Improvement Program.
