The following bugs have been reported and noted since SP2, NIM071964;NIM068933 "The Join Field tool does not match all rows even when a valid match exists. " and SP1, NIM069071;NIM066191 "The environment setting, 'Maintain fully qualified field names,' is not honored when performing an Add Join in ModelBuilder." I don't feel that it's appropriate that work around have to be applied to resolve bugs that have been around since SP1. Regards ... View more

I have read numerous posts where we are looking for an easier way of joining two polygons based where the the majority of the one polygons area lies. ESRI needs to add more options in how spatial joins are made when joining vector layers. We are currently delineating crop fields and  and need to associate the crop fields to the appropriate parcel boundaries. Crop fields are more accurate than parcel boundaries and therefore the crop fields overlap the parcel boundaries. I clean and simple method that does not require you to export your data to excel is required to join polygons to another polygon based on where the majority of the polygon falls within. ...

Currently "Autocomplete" only works on features that are stored within a single feature class. Autocomplete should be able to be used across multiple feature class that are stored within the same file geodatabase or feature dataset. We are currently delineating hundreds of thousands of crop fields and farm dams as part of a water allocation project. The boundaries of the crop fields and farm dams share boundaries in multiple instances. We currently store the features within a single feature class in order to use autocomplete, but have to export the dams afterwards into a new feature class in order to run calculations on the features. Any idea if a tool/script could be created using autocomplete across feature class would be appreciated. Regards ... View more

Hi Everyone I watched a training seminar within the ESRI training site on python for ArcGIS 10. For some reason or other I can't find it again. The training seminar concentrates on whats new in python for ArcGIS 10 and introduction to ArcPy. ESRI demonstrated a python script that automatically re-aligned polygon boundaries that overlaped using a defined tolerance. I also recall comming accross a script/tool within the code gallery while looking for something else that suggested that it automatically corrected topology errors, which again I can't seem to relocate. If someone from the user community or ESRI can guide me to finding the script/tool or how to accomplish this it would be a great help. We are currently delineating crop fields and need to clean up polygons that are overlapping by re-alinging the boundaries automatically using a defined tolerance. There are a large amount of datasets and manually fixing them is not an option. I have found that ETGeowizards can be used, but I would prefer to use a python script that I can be built into my existing process. Regards ... View more

I've developed a methdology based on know my upstream slope of the dam as well as knowing the down stream slope of the dam and the height of the dam wall. I'm able to produce a tin that will represent the dam wall which I then  convert into a raster and substract it from my surface raster to determine the fill volume of the dam wall. I'm looking to improve my methodology. I want to find out if there's a way of automating the generation of parallal lines using my polyline that represent the top of the dam wall for each side. I'm currently doing this mannually at this stage. The polylines are being used to asign the slope for each side of the dam wall, which are then used to generate the tin. Thanks, any advice to achieve this will be appreciated. I've attached a jpeg of the dam wall in 3D to further understand what I'm trying to achieve... Regards ... View more
