In the GPS Preferences dialog, GPS tab, set Protocol to TSIP. Set the port to COM3...that is usually the internal antenna on the GeoExplorers. It will probably be described as TSIP Serial Port. If you have Trimble Terrasync software, you can look at its settings to verify that COM3 is the internal antenna. When you plug your external antenna into the GeoExplorer, the external antenna is used and the internal antenna is ignored. ArcPad will give you an estimated accuracy in the GPS Position Window dialog. Go to the Quality tab. The Zephyr antenna may give you slightly better accuracy over the internal antenna. There is an antenna height setting in the GPS Preferences dialog. ... View more

I have been using ECW format imagery with the ECW extension for a while in ArcPad. This has worked very well, even on 16-bit devices with ECW files nearing 2 GB. The old version 6 extension may work on the newest version of ArcPad. It was working with a beta 10 version of ArcPad. I do have a Windows 8 device with the newest version of ArcPad and can't get the ECW extension to install (even with the special instructions from arcpadteam.blogspot.com.au). ... View more

Go to the My Content area of ArcGIS Online. Click the Add Item button. Browse to your tif file and add it. This is not adding it to a map but just as an item. Then you will have to add the tif file to your map. When you are in the map, click on Add (toward the top left), then Search for Layers, then click the Go button. The tif file should show up in the list. Add it then wait a little while. If your georeferencing and coordinate system are correct, I assume it will fall into the correct place. Paul Lohr ...

That's a good way of getting your result. If your geometry is not clean, you may have strange results. Hopefully the geometry is clean. After the intersect, add a field and use the Calculate Geometry tool to get your lengths. This probably belongs in the ArcGIS Desktop forum. ... View more

Your link calls the map to open in a browser. I would rather have the map open in the ArcGIS app. The formatting of the link below achieves this. Maybe this solves the issue with the browser opening the map - rather, let the ArcGIS app handle the request? arcgis://<organizationName>.maps.arcgis.com/sharing/content/items/<map_GUID>/data Here is a sample map to try on your mobile devices: arcgis://www.arcgis.com/sharing/rest/content/items/5a2cc24bdb9f4af986cac8f2cda1a106/data ...

Unless something has changed, plain AutoCAD does not have a command to export a shapefile. In order to export from AutoCAD, you probably want the mapexport command. That comes with AutoCAD Map 3D and probably with AutoCAD Civil 3D. If you can get Map without Civil 3D (assuming you don't need Civil), that's the way to go. If the surveys you wish to export use arcs, you may want to use ArcGIS Desktop to export the CAD data into a geodatabase. Sounds like you have done this already. I say 'export' but this is confusing because ArcGIS Desktop reads CAD files directly. Arcs are not supported in shapefiles. The arcs are mimicked with short little line segments (tessellated curves?). Paul Lohr ... View more

You may need to host your own imagery on ArcGIS Server. Or find a company who will do that for you. It may help if you post the address of the service where that old imagery is coming from. ... View more

If you are using a GPS that has WAAS corrections, accuracy should be between 10 and 30 feet. Without WAAS...20 feet to 50 feet...? If you are using lat / long values, WGS84 is correct. ... View more

Our ArcGIS Online credits are dropping fast...and it appears to be a direct result of the photo attachments on one of our feature services (about 2000 photos). Can you let me know when this functionality will be available? Has anyone tried to script this? We want to move the whole lot (feature service and photos) to our own server however doesn't look like it'll be happening for a while! Mike Ask ESRI to export your ArcSDE table or database to a format that you can import to your DBMS. You'll want the attachments table and the parent feature class. If you are working with SQL Server, the link below will get you started towards exporting the images from the DBMS. http://www.sqlusa.com/bestpractices/imageimportexport/ Not quite sure, but you might even get the attachment and feature tables as gdb or mdb files. That could work if the photo attachments are converted to BLOB format. ... View more

What about placing multiple points, one on top of another, to represent the "many" side of the relationship? The pop-up on the ArcGIS Online map should retrieve all of the point records with a single click. Not a clean solution but perhaps a workaround. ESRI is terribly slow at getting useful functionality in place. ArcGIS Online has been around for quite a while yet we still don't have something as common as support for one to many relationships. ... View more

It's pretty easy. Do you have a shapefile that uses the projection that you would like to use? If you do, copy that shapefile's prj file over to your GPS device. It might make sense to rename the prj file to the name of the coordinate system. ... View more
