This is the view of the TimeMatching.mdb in ArcCatalog. The lines are the feature class LinkedLines. You should be able to see that and load it into ArcMap. Will post more detail on the queries in access shortly

You started with a point feature. So the approach outlined by Darren is perfect. Actual LAS files are a different thing altogether. If you have a collection of LAS files, create a lasd dataset using Catalog and go from there.

If you need further guidance about the queries in the mdb or anything else, post here.... Good luck.

That any consecutive in a loop of 12 will be quite tricky.

Sorry bit confused here. I can see that Dec14, Jan15, Feb15, Mar15 are consecutive. But how do you know that Dec is the previous year and not 8 month later?

Thanks for the data, I had a fiddle with it. First I used the dnr garmin program to read the gpx track files to points (as text & shapefiles). Then I created a personal geodb (access) and loaded the data from text. Unfortunately, the time stamp info in each file (ltime), won't automatically come in as a time/date field, have to first import it as text, then update it into a newly created TimeStamp field of time/date type. Confusing huh... As I said previously, you can create a series of queries which join one file to the other based on a minimum time difference between them. Have a look in the mdb file zipped attached. From the matched table I used the XY table to line tool to create the joining lines. Then added a distance field, changed the projection of the df to UTM32N and calculated a metres distance / length. Hope this works for you.

Are you correctly defining which is X and Y. Longitude = X; Latitude = Y

If I understand your problem correctly... To get which raster in a stack of rasters has the highest value on a cell by cell basis, then look at the Highest Position tool in SA Tools / Local.

It seems to me that this buffer(?) is similar to producing some sort of elevation isoline above the stream. ie make "contours 1m above the streamline". These are not elevation contours because, as Darren says, the stream is always going downhill. Been fiddling with this a bit, but havn't got any coherent code for this yet. But if anyone has found something which does something similar, then please share a link. Sorry for hi-jacking this thread....

Get portalpy from esri/github. There is a portal.get_org_users() method to the portal object. And a bunch of other useful portal functions

Ah, I see. I don't know of any ArcGIS tools to do this, as its nots really a spatial problem but more of a time stamp matching problem. I have done this in the past for correcting geophysical readings (rover vs base station) and basically did the matching in Access by finding the minimum time difference between records in each file. And I suppose we could also do this in python as well. But some example files would be a help.

Which ascii format is this then? If it is something like *.asc with a well defined header as per this help : ArcGIS Help 10.1 Then the Ascii Grid tool will import this into a raster.

For ArcScan you need the image to be in binary ie 1 or 0, black or white (2bit). A gray scale image is 8bit. So if you have a grayscale, you need to segment it into a 2 level image. ArcGIS Help 10.1

And, thinking about this a little more.... Surely, the cell size (in ground metres of whatever your standard is) can't be specified before geo-referencing anyway. Before that step, the image is just pixel units.
