i think i found out why I wasn't able to access my arcgis.com webmap from a template on our local webserver....yesterday at the esri SWUG I found out that only silverlight viewers have the ability to login to esri global acct, to access private web maps. how...i'm going to a tech. workshop today on silverlight to find out! thanks again Mike! ...

hi mike- As far as I could tell, the 8th post in that thread just refers to access secure (https) arcgis-server services, not private services on ArcGIS online. ... View more

thanks mike. However, i'm not connecting to any secure ArcGIS Server services, I just added all layers to the map via .zip shapefile. I'm trying to connect to the Arcgis.com map that i have saved, (shared with a private group) from a custom template I have on our webserver. I understand this is accomplished with tokens but i'm not able to get it to work. ... View more

any update on this? I have a non-public map saved on arcgis.com. i generated a token using the following url: https://www.arcgis.com/sharing/generateToken?f=json&request=gettoken&username=MYUSERNAME&password=MYPASSWORD&Referer=MYUSERNAME token = ttttttttttttttttttttttttttttttttttttttttt I then found the ItemID of my non-public map. ItemID = xxxxxxxxxxxxxxxxxxxxxxxxxx I am able to view the json using this url: http://www.arcgis.com/sharing/content/items/xxxxxxxxxxxxxxxxxxxxxxxxxx/data?f=pjson&token=ttttttttttttttttttttttttttttttttttttttttt I downloaded the chrome legend map template from here and installed it on our webserver: http://www.arcgis.com/home/item.html?id=c9f1750f9b9f496ca7df16fa31870145 I can view the default webmap when pointing to our webserver's URL. If I open the template .html file and alter the webmap setting, to point to a different, publicly available map, it works great. However, when I alter the webmap setting in the .html to the following: xxxxxxxxxxxxxxxxxxxxxxxxxx/data?f=pjson&token=ttttttttttttttttttttttttttttttttttttttttt I get a login box, of which i enter my arcgis.com username/password, (same that was used to generate the token) and it just says 'username/password invalid' any ideas?? thanks! ...

thanks! confirmed. If I create a new feat. dataset with smaller tolerance, (0.0000000089 degrees) then import the feat. classes, no self intersections are found. Too bad you can't set tolerances; going to have to recreate thousands of feat. datasets; then import the feat. classes. ... View more

more info.... If I create a new feat. dataset, then import the feat. class that contains self intersections, and re-run check geometry; no errors are reported! Could someone explain? ... View more

thanks Jake. Yeah, unfortunately, most of the feat. classes I need to check are polygons ... View more

not the most elegant solution, but to calc. geometries of an unprojected feat. class, I ended up: projecting feat. class - output to temp.gdb calculated geometry of temp feat. class make feat. layer of temp feat. class join temp feat. layer "OBJECTID" ----- with ----- original feat. class "OBJECTID" calc field of orig. feat. class with the calculated geometries ...

depending on how many gdb's you have, this can be done in ArcMap...manually. 1. Start with a new ArcMap document, then double click on 'layers' in the table of contents 2. in data frame properties, go to coordinate system tab/ predefined/ geographic coor system/world/wgs84 3. hit "ok, then "yes" on the warning 4. add your feat classes 5. create 2 new fields, named 'lat' and 'long' 6. right click on the field and choose 'calc geometry' 7. select 'y coordinate of a point' then select 'use coordinate system of the dataframe' units 'decimal degrees' 8. you now have a column of latitude coordinates. 9. do the same for 'long' field. remember, x measures distance E/W of Prime Meridian, y measures N/S of equator ...

humm, created 2 polygons inside a feat. class. OBJECTID = 1 was created using the "end arc point segment tool" and OBJECTID = 2 was created using the "straight line segment" tool. Ran this script: fclist = gp.listfeatureclasses("arc_test*")             for fc in fclist:                 rows = gp.searchcursor(fc)                 row = rows.next()                 while row:                     typ = row.Shape                     geom = str(typ.centroid.X)                     print row.getvalue("OBJECTID"), geom                     truegeom = str(typ.truecentroid.X)                     print row.getvalue("OBJECTID"), truegeom                     row = rows.next() Here is the output: 1 -93.0638463269 1 -93.0638463269 2 -93.0635589449 2 -93.0635589449 both geom & truegeom are the same, for both polygons, even though 1 of them contains an arc segment?? ...

this should get ya going. I didn't see the need for the .describe since your end goal is to loop through datasets/features anyway. Take note of the "*" wildcards in the listdatasets and listfeatureclasses methods. You could enter "utilities*" to only loop through all feat. datasets that begin with "utilities". dsList = arcpy.ListDatasets("*", "Feature") for dataset in dsList:     arcpy.env.workspace = sde + "\\" + dataset     fcList = arcpy.ListFeatureClasses("*")     for feature in fcList:         arcpy.env.workspace = dataset + "\\" + feature featout = output + dataset + "\\" feature print featout arcpy.Project_management(feature, featout, outCS, transformation, inCS) ...
