Digital Shoreline Analysis System - Error

ShamsaKanwal — Tue, 09 Oct 2018 03:27:32 GMT

Hello I am working with digital Shoreline Analysis System software developed by usgs for coastal zone analysis. When I try to generate the statistics, I get the following error message: Shoreline layer "all-coastlines" has some record (s) that do not have a valid date specified in date field "date_". - I check: the date setting of my Date_ filed (MM/DD/YYYY), the dates are in this same format in my "all-coasltines" file too. - I tried to remove the "0" before the figure of the month (4/03/1989 instead of 04/03/1989) but no success.- The field "date_" is in text format, with 10 characters. I also tried different options with 22 length by adding times but no success.

Has anyone come across this problem?

Without knowing anything about this digital shoreline analysis system, have you checked the table contents in field Date1? Correct the invalid entries (perhaps Null) might be the place to start.

Yes. content has no issue. In fact I tried other solutions to check which record has problem for example splitting the date into halves and tried to identify the invalid records but it did not resolve the issue

Any solution to this issue? I just ran into the same problem.

In DSAS the dates must be 10 characters long. So 4/3/1989 MUST be expressed as 04/03/1989.

"An unexpected error occurred. Please refer to the log file (C:\Users\Amine\AppData\Roaming\Corona Environmental Consulting\DSAS v4.4 add-in\DSAS_log.txt) for additional details after closing ArcMap. I am asking for a friend, how to fix this error?

Did you get the solution? I'm facing the same problem

I am having this same problem. I cannot figure out the issue.

I had the same problem, and I solved it by working on preprocessing. My steps were:
Digitalize the shorelines (with a fixed zoom scale) and create one baseline in the continental part, you may have to create in both continental and water parts (depending on our region). It is necessary to use shapefiles in the same coordinate system, and it must be based on meters (UTM).
I used the ArcGIS 10.8 and DSAS v5.
In the case of your shorelines had been digitalized in different shapefiles, use the "Merge" tool to join all shorelines in one shapefile.
In ArcCatalog, click with the right bottom in the folder you want to put your geodatabase, so go to "New" and in "Personal Geodatabase". After that, with a double click in the archive just created, click with the right bottom in the space of it, and go to "Import" to put there two shapefiles, one with your shorelines and other with the baseline(s).

Some classes and its types are needed, so you should revise if your shapefiles has:
- Baseline:
--> Created by the user: id (Long Integer)
--> Created by the DSAS through Attribute Automator: SHAPE_Length (Double), DSAS_ID (Long Integer)

- Shoreline:
--> Created by the user: id (Long Integer), Uncy (Double), Date_ (Text).
--> Created by the DSAS through Attribute Automator: DSAS_date (text), DSAS_uncy (Double), DSAS_type (text)

I let the uncertainty(Uncy) camp empty, and the DSAS use 10 meters as default in this case. After that, I used the video of DSAS (https://www.usgs.gov/media/videos/introduction-dsas-v50-sample-data-workflow) as guide.

Did you manage to sort the issue? I am having the sam problem. The solution provided by LaurenFCruz did not work.

Indeed, this format is exactly what needs to be entered, thanks!

Be aware of :

-> backslashes as a separator

-> actual days, not 00/00/2020 like I did which gives an error

-> like mentioned, exactly 10 characters

First, you need to check the log in the given file path, scroll at the end of the log and look for error messages. A pretty common/silly one is the date format in the Date Attribute. Please look at @Katherine_Ames 's answer above (and my reply for specifics) for more details on that matter.
