This sounds exactly like a projection issue, CoreyMacIssac1. Try adding your polygon shapefile to a new, empty map, and see how it displays. If it appears as expected, this verifies my assumption that it is projection related. If this does not provide the information you need, post your shapefile, and perhaps I or someone else can provide a better response. Regards ... View more

This is a matter of personal preference. Personally, I would place it in the legend as "AP (Airport)" If the resulting legend becomes too big, I would add a notes text item such as "Notes: AP = Airport" and any other abbreviations you need to explain. Regards ... View more

You need to choose a feature attribute hierarchy. What you create with overlay analysis requires this as a follow up process, as it will return the overlap as a separate polygon. If you can not create a hierarchy, then run a union analysis, and display the overlap as a different symbology to indicate your area of uncertainty. Regards. ... View more

I am not certain I fully understand your needs. I have created a copy of a feature class in the map, set my symbology to reflect what I want in the legend, set a definition query to FID = -9999 (which returns no features). Then I used that item in the legend instead of the more complex feature class. This allows you to customize the symbology and text in the legend, independent of the actual feature class symbology and text used in the display. ... View more

RhettZufelt has provided the correct answer. If you are still having issues, be aware that having the excel file open in Excel puts a lock on the file and prevents ArcMap from interacting with it. In addition, another instance of ArcMap that is open and points to the Excel file will put a lock on it, preventing interaction with it. Closing these links should enable access to the Excel file. ... View more

Thank you for your response, Bert. Do you know the unit performs under moderate canopy and close proximity to structures? Jim Cousins GIS Project Scientist S.S.

I have been looking at this myself. I am still trying to get the real costs and specs, but the Trimble Catalyst seems a possible solution, for my needs anyway. It is certainly very affordable, but this depends on your collection needs. It is basically an antenna ($350) that you connect to your smart phone / tablet. You acquire a subscription to the "Catalyst service" which has a stepped cost depending on level of precision needed, from $40 to $350 per user per month. This subscription can be annual or "on demand". Still figuring this bit out, and an accuracy assessment for different collection environments, like amount of canopy cover, and building shadow. I am interested in what your final selection is. - Jim ... View more

You need to enable "jump lists". Right click the taskbar, and select "Taskbar Settings". In the next window choose "Start", and at the bottom, enable  "Show recently opened items in Jump Lists on Start or the taskbar". Regards, Jim ... View more

Select the features you wish to, right click on the source layer and choose >> Selection>>Create Layer From Selected Features. If you wish this to be permanent, export the resulting layer to a new file. ... View more

Ashley Peters, any additional information? What type of layer is it, or is it all layers in the map? It sounds like you have addressed any potential problems with the ArcMap installation. Does this behavior occur in other map documents, or just this one? If just this one, you could run MXDdoctor (in your start menu under ArcGIS) against your map and see what it comes up with.

David has a point. If you have not added the 2007 Office drivers, an xlsx file is not readable in ArcMap. This link addresses the .xlsx format: Understanding how to use Microsoft Excel files in ArcGIS—Help | Documentation  Regards, Jim ... View more

there is a tool ArcToolbox >> Data Mangement tools >> Features >> Add XY Coordinates that will add and populate X Y columns in your shapefile. Beyond that, what do you mean by "Is there a way to read out the coordinates of individual points on Arcmap?" Regards, Jim ... View more
