Thanks Dan. Exactly, there are large gaps in the data temporally. I am now thinking of using a Gantt chart to display the data although I'm not looking forward to organizing it so that it will easily be represented. I'll have to brush up on my Microsoft Project skills I guess! I assume there is nothing within ArcGIS that can accomplish this task.

Hi all, I have some acoustic tag data for shark movements where there will be a record at 1 of 32 acoustic 'listening stations' with time and date. I have used tracking analyst to create the points and lines showing the movements of each shark. What I would like to do is show when the shark was at each receiver and for how long it may have stayed and then when it was recorded at the next receiver. I was thinking of creating a graphic with a simple line as a timeline (ie/ Dec 2010 to Dec 2013) and simply notate with a dash and label for which receiver picked it up at that time. I'd like it to be 'true' as in data-based distances between each dash. Does anyone have any ideas what I could try to accomplish this or other ideas for quickly representing the same thing? Many thanks, Jeremy

Yeah, that makes sense. I think even if there was a script tied to a new polygon where it took priority over everything behind it and automatically clipped the underlying polygon. This way I wouldn't have to select clip every time.

Sorry for not being clear, I'm trying to separate that sand that is within that polygon from the small fingers of coral that surround them. The extract by mask tool would work if I was clipping a raster but i'm trying to create a sand/reef polygon based on the imagery. It may be that I have to continue trying to classify it although I don't have access to the high resolution imagery as it is coming off an image server and the size is very difficult to work with when exported.

Thanks Kyle - yeah, that's what I've been doing thus far. I'm creating a new polygon using streaming vertices and then using the clip function on the editor toolbar. It does work although I was hoping to avoid the need to 'clip' the background polygon somehow to speed up the process. If there was some kind of 'eraser' of the background polygon using a brush of a certain width, I think that would be ideal. It is possible that it just doesn't exist!

Thanks Chris. It looks like the polygon editing tool isn't available in the free version of ET GeoTools. Also, I tried using it and it looks like there is no 'streaming vertices' available when editing so it would be difficult to digitize multiple polygons. I do use ET GeoWizards often and can recommend that as well for geoprocessing.

Thanks for the reply Mitch. I don't have the two layers separated as yet but if I did then I would use the erase tool for that for sure. Here is an example of what I'm trying to separate.

Hello, I'm wondering if anyone knows of a third party tool or something built into ArcGIS 10x that will erase or clip an area of a polygon quickly and efficiently. I'm thinking something like the 'magic eraser tool' in Photoshop. I'm trying to manually digitize sand within reef communities and as it stands I'm digitizing a polygon over-top of the the wider 'reef' polygon and then clipping the underlying data... all the while thinking that there has to be a better way of doing it as there are many areas. These are areas where image classification isn't working out well. Any thoughts are appreciated thank you.
