Hi, so I have a full post/zipcode dataset of over 1,000,000 features. However I want to filter out and consider only about 1500 of them. These postcodes have no common attribute but the exact postcode is in both the attribute table for the full dataset shapefile and in a column of the excel table. Could it be done by adding a column to the excel table populated with a one, attribute joining the table to the shapefile then filtering the shapefile by the 'one' attribute. Then I could create a new layer based on the selection? Not exaclty sure that would work, but if anyone has a solution or tweaks it would be much appreciated. Thanks ... View more

Hi All, I've attached a screen shot of the first steps of a model I'm trying to build. This is the first time I've used model builder so don't know much about it. However, I'm trying to put the data through the first tool, which is a tool from outside of the ESRI system toolboxes and then put the result into the next tool. I hope this is not to difficult, but could someone help me out please? Thanks ... View more

I have a set of buffers from 5-200m from a scheme at one metre intervals. Is there a way to make each buffer a ring, one metre wide, around the scheme? Alternatively, if I create new multiple buffers around the scheme which align with the existing ones, is there a way to spatially join the layers, but so that the attributes of the topmost existing buffer are the only ones retrieved by the new buffers? Thanks, Ellen ... View more

Hi, I'm working on a project for which buffers have been created around a line scheme. Each line has 100-200 buffers at different distances. However, I need each of the buffers to be clipped to the extent of those inside of it, so each buffer is a ring rather a solid polygon. Each of the lines in the scheme has these buffers, but because the lines meet at certain points, the buffers from different lines also intersect, However, I need buffers which are the result of different lines, to ignore each other in the clip. Does anyone know how this might be done, either by script or by the toolbox? Thanks for any help ... View more

I'm looking to build a fairly basic web-app which gives information about features of a certain location. I have a colleague going on holiday to an area i know well so was going to log a set of 'Easter Eggs' that he might miss. However, I was hoping to publish the app so that it works in a similar way to the geocaching app. Whereby, when you get close to a location, the app recognises it is close to that point and automatically brings up information about it. Is this possible when building a simple web-app using a template in ArcGIS online? I've never done it before so really have no idea. Thanks ... View more

I have a set of point data containing attributes for their assignation code and the number of each feature found at that particular point. I want to label the features with both of these attribute concatenated together. eg; if the code is BC and the number is 12, the label reads 12BC. How do I set up a new attribute which combines both of these so I can assign the labels. Also, is there a way to filter out the concatenation where the number value is 1. eg; code = BC, number = 1 resulting label = BC? Thanks ... View more
