With the current tools, What structure types do you support? Will I be able to pick different structure types other than lattice tower, and place them on the locations I picked or on the locations specified in a spreadsheet or shapefile? Thanks!

I like the legend feature that easily shows the number of feature in the map extent for each feature type. It will be great that the legend can show other statistics info for each feature type, such sum of shape.length for lines and sum of shape.area for polygons. They should be bascially same (all are statistics information you can obtain by "summarize"), however, only count can be shown by default, without customization or coding. In the future other statistics info like total length and total area should be also options to show. It will be a huge plus to create report maps or add summary to the map without having to create a seperate summary table.

Thanks for your JSFiddle example. It is pretty neat to try. However, when I try to print with overview selected, I got a blank PDF. Could you please fix it if possible? I need to create a custom print layout with an inset, however, the map is only showing on the active frame. Is there something I should do so the map will appear on both frames?

I wonder if you figured it out or not, but it is doable, like in the code snippet: if (HtmlPage.Document.QueryString.Keys.Contains("xVal1")) xVal1 = HtmlPage.Document.QueryString["xVal1"].ToString(); In the URL, you pass something like aspx?xVal1=100, or even htm?xVal1=100 to the code behind. Z

However, IFeatureSelection doesn't work with IEnumFeature. What to do? I have to use ISelection instead. Are there any other ways?

Is that because you didn't set up the workspace? I am having the same issue while trying to use a customized tool in my c# code. I think the error means that the code is trying to access some object that is out of bound or can't be found. However it is too generic and doesn't help with debugging. I tried to find the usage and validate messages from the gp tool but with no avail. Anyone got a solution or suggestion on how to trouble shoot? Thanks!

Dear fellow parcel editors: To be able to construct a curve using COGO, you would need radius, chord length and chord direction, for example. What if you miss some information (like chord direction)? Will Parcel Fabric be flexible enough for me to continue without that info, then get back to fill in the missing information? What we are doing now is to use a different start point, then go all the way back to the curve. Thus we can close the parcel without needing the chord direction. However, if the traverse consists a couple of such curves, then we are at a loss what to do. Can we start serveral new segments, then somehow link them together? Do you have such an experience and figured out a solution? Please share with us. Thanks in advance. Danny

I think that is sth set by design. If you turn the group layer on, all the layers in the group will be turned on. If you turn the group layer off, all the layers in the group will be off. So how to turn on/off certain layers? I think that you don't need to worry about the group layer, just turn on/off the certain layers should work. At least this is my experience with ArcGIS Desktop. I think this should hold true for java script api too. Please try my idea and see if it works.

OK. Here is the deal: ArcSDE will not support multiple types of databases on a server, even though it can support multiple databases of the SAME TYPE. I already have SDE databases on a sqlexpress on the same server, that is why I couldn't connect since there can be only ONE SDEHOME. I know that it is not recommended to have two different types of databases on the same server for performance issues, but I wonder if it is possible now as the server/virtual server/cloud server is getting much more powerful. Still interested in though what is the update status of postgresql and postgis for sde 10 sp3.

Is there an official date of ArcSDE 10.1 yet? What is the latest version of Postgresql and PostGIS that SDE 10.0 Supports at the time being? There is no installer for Postgresql 8.4.1 as mentioned in ESRI document. So I used postgresql 8.4.9 installer instead. However, I got a database connection error when I tried to post install SDE 10.0. Is there way to get around? Anyone succeeded with a different version than ESRI specifies for Postgresql or PostGIS?

After several tries, I got flex viewer heat map working for my own layer. I realized that I had to include the <defaultquery> 1=1 </defaultquery> tag to be able to show all the points and refresh the browser. I also got some basic query done, thanks to Lloyd's guidance on query, many thanks, guys. I am going a little bit far now: Can I query based on two different fields (first is type, second is status, in my case). I think I would like to try and find out. Probably would need to add another query in the heatmap widgit or create another similar "widgit"? Are there better/easy ways to do multiple queries?

I tried to use my own point layer (arcgis server map service) to replace the earthquake layer as the heatmap layer. I replaced the earthquake layer url with my own url, but it returned 0 feature. What else do I need to check or modify? (I tried to remove the query part in the xml) Do I need to recompile the code? So far I just need to display the points (headmap) without query. Maybe later on I would like to query by the points' type information or a frequency attribute. The viewer looks really nice. I am interested in customizing it for our purpose. I wonder what kind of customization needs recompilation (using flex builder), what customization is just as easy as replacing links or variables and doesn't need to recompile from source code. I am trying to find out myself, but some tips will be very helpful. Thanks!

Has anyone done conversion from screen coordinates to map coordinates using pure REST API? Could you please share your experience? Thanks!

‎07-20-2011

We don't want to use either web APIs (java script, flex, silverlight) or soap API or web SDK, just pure REST API to do map navigation and query for our ArcGIS Server java enterprise application. Will this work? To be more specific, We have a java application where we use exported image from ArcGIS Server in our map panel. Now we want to be able to zoom in/out and identify on the image we have. How can we find out map extent or map coordinates information from ArcGIS Server REST api for a click or zoom/pan on the image? If we can do this kind of conversion from REST API, then we would be able to get a new image or do query based on this information too--- I have searched ESRI documentation but haven't found a way. Did I miss something or I have to find a way around? Thanks for your opinion!

I am glad that the new Arcgis Explorer can open kmz files directly. It is able to show points, polylines and polygons as well as georeferenced images (sample maps or imagery from other sources) wrapped up in the kmz file. I like it very much. However, when I want to export the files inside kmz, I can only export points, polylines and polygons. There is no way that I can export georeferenced images. I did get around by "sharing" the images as bounding polygons, but often time their projection gets messed up and I had to spend a great deal of time to adjust them. Wouldn't it be nice if I can export georeferenced images in kmz directly and keep the right location information? I wonder if ArcGIS 10 desktop can directly add kmz and do all that I describe above? Do I need an extension or is there better/easier way to do it. I just don't want to georeference it again if it already get georeferenced in google earth.
