Web Analytics Made Easy -

Node Dangles


I was working on a project and wanted my own custom mouse cursor and did not easily find a way to make your own in ESRI’s instructions. But, once you know how to do it, it is pretty easy. In Visual Studio, Add a New Item: Add a Cursor File: You can edit your cursor with the editor program in Visual Studio. Once you satisfied with how it looks, make sure that the Build Action on the cursor is ‘Embedded Resource’.
Discovered something today. I was working on an arcpy script that copies a raster dataset from a file geodatabase into a Postgres SDE geodatabase and then does some boring routine tasks–building stats, creating a mosaic dataset, adding the raster to the mosaic dataset and making a couple referenced mosaic datasets. It sometimes has trouble with the initial step of uploading the raster because of the sheer size of if (1m elevation raster for counties) and it failed today on one.
I am working on an data-entry application to edit feature classes that contain several coded-value-domains. The problem with some of the domains, however, is that some entries have been added after the initial creation. So the first 25 entries are in alphabetical order and there are some stragglers at the end that are in the order they were appended. This can be confusing for users–they go to select ‘Milli Vanilli’ and look between ‘Madonna’ and ‘Motley Crue’ but can not find their favorite band there–they have to go to the end of the list to find their selection.
For some odd reason, I wanted to split all the arcs in a polyline feature class to a specific length–if a specific feature was longer than the target length, it would become two or more separate polyline records. Here is the bare-bones script that copies an existing feature class into a new feature class then processes each record, splitting it into multiple records if the polyline is longer than the user-specified tolerance.
One of the Spatial Analyst tools we often use in ArcGIS is the Extract Values to Points tool. This allows us to take a point file (well locations in our case) and attach a value (elevations) from a raster image (a DEM) to each point. Today I was running it for the first time against an Image Service we recently published and I received a warning message,‘WARNING 000957: Skipping feature(s) because of NULL or EMPTY geometry’.
In migrating a toolbar consisting of a button and a couple of tools for use in ArcMap 10, I decided to take advantage of the ease of deployment enabled by add-ins which was introduced in 10.0. So far, I’m loving the functionality. One thing, however, that I have to figure out is that the controls are not instantiated until they are clicked on. One of the results is that the controls, by default, are enabled.
I was working my way through this ESRI Walkthrough: Building custom UI elements using add-ins (ArcObjects .NET 10 SDK). And came across a couple minor errors that I had to correct during the process. First, while implementing the OnClick() code for ZoomToLayer.vb, Visual Studio gave me a ‘Name ‘ArcMap’ is not declared.' error. In the walk-through, they mention that the ArcMap method of your class. For me, however, it appeared under the .
I have been working on some data entry forms that utilize a DataGrid. Using a PostGres Geodatabase that had domains set on several fields, I could not directly bind to the controls on my dialog. So I am going the round-about way of populating my own comboboxes with valid names and displaying within the DataGrid. Having not done this previously, I found this example: Example of how to add controls in data grid VB.
I have been working on updating some data that was published using Arc/Info Workstation Export (.e00) files, converting them to shapefiles, or in the case of annotation, to a geodatabase feature class. While converting some INFO tables, I have received this error: It turns out that Workstation can create export files that contain values that did not fit within their field–I’m guessing that somehow you are actually able to enter invalid values into those fields but I did not confirm that.
