The zipped file you posted seems OK.  I brought it in and it lines up fairly well with other California data I have from several municipal sources (some of the boundaries are along County lines).  It does not appear that the Teale Albers assignment is an issue. May I suggest that you start a new mxd, then bring in the Climate change file first.  This will automatically set the Data Frame properties to the Teale Albers assignment in the shapefile.  Then try to Add XY Data the csv file and see if the points come out where expected.  If that does not work, let us know how it is off as there are several places where things can go awry.

If you are asking on how to make new point symbols (i.e. different ones than the default), I would suggest looking at the available Symbology help files.  There are many existing symbols that come with ArcGIS, plus you can make your own within the software (and even buy some pre-made ones from third-party vendors, like fancy state-specific highway shields if you want).

Do you need the Stationing to reset at each bend?  In other words if a polyline travels 87 feet then makes a 90 degree turn, you want a 87' station mark there, then the next segment starts at zero feet and continues upwards until it hits a bend?  If this is the case, one can employ the Split line at Vertices (Data Management) geoprocessing tool to break up the line into segments, then redo the Stationing for each segment.  Note that there may be a need to recombine some segments after running this tool if there are vertices on straight portions. ArcGIS Desktop Another workaround/idea when using ET Geowizards stationing - make station points at a smaller interval then what is really needed and then weed out the station points you don't need.  For example, do 1-foot intervals, then select and delete the unneeded ones.  If I recall correctly there is an attribute created with the stationing which has the distance (ET_ID?), which aids in sorting it down.

What exactly is a "PI" and what affect does it have on the stationing? Chris Donohue, GISP ... View more

Another option is to use the Grid Index Feature (Cartography) geoprocessing tool.  To get the proper extent, one can add a feature class that covers the extent needed to the Input Features (optional) part.  Use the Environments button on the bottom to set an appropriate projection/coordinate system that will line up with True North.

As Dan Patterson mentioned, this problem has a myriad of potential sources, so without more information, it will be hard to provide an relevant answer.  So, with that in mind, can you provide some basic information: Which GIS software are you using?  ArcGIS?  ArcGIS Pro? What Version is the software?  10.4, 10.3, 10.2.1, etc? What type of Geodatabases are you working with?  Personal Geodatabases?  File Geodatabases?  Enterprise Geodatabases (SDE)?  Some other format?  Another file type, like a Coverage or Shapefile? What Version of Excel are you working with? What Version of Access are you working with? You mention that some of the data cannot be accessed.  Does only some of the data transfer over, with some missing?  Or is none of it transferring over? What specific processes/tools/functions are being used?  In using these, do you get any error messages, and if so, what are they? Chris Donohue, GISP ... View more

Double?  That also seems weird.  Are we going to decimals in addresses now?  Do we really need that much precision?  I can just envision a conversation like this: "So, where do you live?" "I live at 160.25120466 Main Street...." Chris Donohue, GISP ... View more

Do you have access to the Spatial Analyst extension?  If so, there are several options available to combine the DEMs.  Here's two I can think of: 1.  DEM to Raster each DEM, then Mosaic to New Raster. 2.  Use Raster Calculator to combine them. I believe there are several other options available, but on this I am not so knowledgeable.  Let me add some folks who know way more than I do about this: Darren Wiens Dan Patterson Chris Donohue, GISP ...

Assuming your project site is in the United States, one option is to download the data for the quads you need, combine them so you have full coverage in one dataset, then run the Cost Path Analysis.  I believe you can find DEMs here: The National Map Also, it was possible in the past to get a seamless DEM from the site seamless.usgs.gov, but that now directs one to the same National Map link above.  Since the changeover I have not tried to get a seamless DEM, but that functionality may exist in the National Map, so poke around a bit.

We only have numbers (Long data type) in our Street Ranges (City of Roseville, California).  Any letters as part of a street address would go in a separate StreetNumberSuffix field or Unit field, but definitely not in a range field (i.e. not in FromLeft, ToLeft, FromRight, ToRight). It does seem like having letters included in the range would throw the interpolation.  Maybe they have an advanced process included in their software to somehow account for it?  Or a basic process to strip it out before interpolation? Just a thought - by any chance are you going to New World Systems Aegis CAD?  (that's what we are starting to use here). Chris Donohue, GISP ... View more

As Dan mentioned, the Erase geoprocessing tool is the way to go, assuming you have an advanced license available.  If you don't, another option is XTools Pro, a third-party add-on to ArcGIS.  They have an Erase function that works with lower license levels.  You can always try the demo version to check it out.
