Hi, I'm going to develop an Add-in (or Extension?) for ArcMap that will include a custom non-Modal window opened by clicking a button on toolbar to enable the user entering some data and interact with the map and layers extracting geometries and perform some geometric calculations. Regarding the above I have two questions: 1. Would the above description require an Add-In or an Extension? What are the differences and limitations of one and the other? 2. What would be a better approach, to use ArcObjects or ArcGIS Runtime? Also, since there is no ArcObjects help available on the ArcGIS for Developers, I was wondering if ArcObjects are getting deprecated? Thanks!

I would support adding pip and/or easy_install rather than including too many third party libraries. Using pip or easy_install is super easy and quick to install whatever library you might need.

Yes, that would be very useful!

This is nice if you add baseMaplayer manually as a separate layer. Is this possible with baseMap gallery widget? I'd like to add a slider that would set opacity on whichever baseMap layer has been selected from the widget. edited: just figured it out. this is one way of doing it: map.getLayer(map.basemapLayerIds).setOpacity(0.1);

Nobody actually answered the question: Is it possible to create a ArcGISDynamicMapServiceLayer from map service published from ArcGIS Online? Thanks,

Could you provide some sample data please?

What Yvo probably wanted and what I'm trying to do as well is to access data in the destination table related to the origin table via relationship class using arcpy cursors. If I set the cursor on the origin feature class, I can only retrieve the field values that are physically stored in that table. But I need to access the data from the related record(s) in the destination table as well. Similarly than you can browse the related data in the identify window in ArcMap. Do I really have to treat the two tables separately and reestablish the connection manually using two cursors and then running the search cursor in a loop to retrieve data from the destination table as Russel suggested?

Hi, I was getting the same error: 00143: Background server threw an exception while overlaying linear route events (Overlay Route Events). The problem was caused by the null values in some "from" and "to" fields. Fixing the data solved the problem in my case.

Finnaly, I have solved the problem. All attempts inside the geoprocessing (arcgisscripting) failed even if I constructed compeletely new objects from scratch setting vertices' coordinate values. So, I resorted to Osgeo.ogr library to create new shape file. The data had been imported using WKT data format (mustilinestring). The order defined in WKT format was preserved in the newly created multipart polylines. Thank you,

Hi, let me rephrase my question. I have many short polylines that I want to assemble into one multipart polyline in certain order. The consecutive number of each polyline is stored in attribute table. My function reads the individual polylines in that order and adds them to the array object which is latter on assigned to the multipart polyline geometry. However, when I try to analize, that way generated, multipart polyline from beginning to the end, it does not proceed in the same order. How can I define the order (first, second and so on) of segments which constitute multipart polyline? Thank you,

Hi, I have a polyline layer that I want to dissolve based on a attribute. If two polylines with the same attribute value share common node they are combined correctly into one new polyline. However, if for instance, three polylines share the same node (branching) or if one of the poylines was already a multipart polyline, the output is a new multipart polyline. Is there a way to control the order in which linear objects are combined into new multipart polyline? In my case, if the newly created multipart polyline contains at least one branching, the order of subsections is completely random which makes me hard time analysing them. Thank you,

Thank you, Bruce! That's what I've resorted to: I created grid using python and osgeo.ogr, union and area calculation are yet to be done. Python comes in handy since I need to do it for 1000+ layers. BTW, not sure if I understand that Dodt's opinion of Python - sounds like criticism. If that's so, I strongly dissagree :-)) Best,

Hi, I need to overlap a grid over the polygon layer and calculate the sum of polygon areas for each cell. The output should be a raster layer. So, I have only polygon layer and need to create raster showing sum of areas in each cell. The problem is similar to LineDensity tool for lines, but I can't find the appropriate tool for polygons. Thanks for your suggestions,

It is much easier than I had anticipated. 🙂 For some reason, I had overlooked the "Side Type" parameter at Buffer tool. When you realize that, the rest is a three step process: 1. Create buffer on one side 2. Create buffer on the other side 3. Combine the two Check out the code.

‎09-23-2010

Has really nobody had that kind of issue, or my question wasn't clear enough? Basically, I need to crate a buffer of linear objects with different widths on each side... Any ideas? Thanx.
