@zeynep In what aspect are they not enough? I doubt you will find a model that includes all the parameters you list above.

comment Urban Hydrology Using With GIS
About parameters, you can go at it from two ways. 1) Use the data you have, analyze how good model you can create (and do it). If the result is good enough, you're done. If not as good and detailed as you hoped, get more data. 2) Define what data and level of detail you need for your analysis and make sure you have it before you start. Exactly what you need is depending on the purpose of your analysis. Not having enough information is a pseudo-state, either you use what you have or you make sure you get more data. There's no in-between.

comment How to change properties of an item in a legend in ArcMap 10.2 using python
@davehughes87 it is greyed out then, but you don't necessarily need it. Just pick a predefined style in the list (e.g. the highlighted in the image above) or create your own. That you can do.

comment Searching semantically for symbols in ArcGIS Desktop?
There are also a number of fonts (that all start with ESRI...) that you can use as character marker symbols. Not sure all of them are referenced in a style. I usually find what I need there, but it takes some time to go through them all.

comment Alternative to Symmetrical Difference (Analysis) in ArcGIS for Desktop?
The Erase tool is also worth mentioning in this workflow, both from within ArcGIS(Advanced licence) and from ET Geowizards(free).

Could you elaborate a bit to help future readers? How did you configure it for everything to work?

comment Working with AutoCAD Layers in ArcMap
@Subin layer names don't transfer from CAD to ArcMap unless you do a conversion with something like FME. So a definition query won't work. However, if you do have a way to get the layer names into ArcMap I'd really like to know!

comment Working with AutoCAD Layers in ArcMap
Unfortunately, that is how ArcMap reads CAD files. It can't (to my knowledge) distinguish layers in the dwg and display them as separate layers in Arcmap. I use FME to convert dwg to shape, that'll give me < 4 shapefiles per dwg layer (one per feature type that contains data). FME aint free, but you can download a trial version.

comment Subtract two daily rasters based on name using ArcGIS ModelBuilder?
@ChristianH If line 9 is image_c =..., it is probably the typo there causing problems. Should be image_b (with underscore) instead of image-b. If line 9 is another line, there's more to fix..

@ChristianH Try changing Raster to arcpy.sa.Raster instead then (although it should not be necessary since you import it on the second row).

@ChristianH You have to edit the script and add your file names and paths.
