You may find it useful to review the entire map creation/uploading data process, before reading this post. To do this, please click here. Otherwise, just follow our step-by-step error correction guide… Why are there errors?
Most upload errors occur our Geocoder does not recognize the address data in a spreadsheet. However, eSpatial has built-in solutions to help resolve most data problems. Let’s begin at the upload progress screen:
The green bar above indicates data that has been successfully uploaded. The pink bar indicates how many errors have occurred.If there are a high number of errors (that run into thousands) you might want to cancel the upload and review your .csv spreadsheet, since to continue the upload would mean eating up your daily upload allowance.
When the upload is complete, you can see that there are a substantial number of errors in our file:
The easiest way to reduce the number of errors – and one we recommend – is to click on Reduce Target Accuracy. This will bring up an accuracy slider:
You can move the slider to the left to reduce the accuracy level. In this case, we’re reducing the accuracy level from ZIP code (high) to country level (medium-low):
When we hit OK, we can see that the level of error has substantially reduced. It’s gone from 172 to a much more manageable 6:
At this stage, you can accept the 6 errors and go straight ahead and map your good data (click Map My Data) or you can click Edit Dataset, which will help you resolve the problems with the 6 remaining data items. This will bring up a screen map with listed error fields to the right:
There are two types of error, indicated by an X (for data that could not be located at all) and ? (for data whose accuracy level was below the tolerance level that you set with the slider).
There are two ways to correct an X error. Simply click on the record and edit the content of the uploaded data:
Another way of correcting the error is by manually finding a location on a map. When you click on the data item (as in the image above), an X is generated, which you can move with your cursor. You can also zoom in on the map to find a specific location. In our case, we’re looking for Amarillo:
Click again to lock the location and release the X. You can see that the data record has automatically been filled in by just placing the X at the desired location. Now all you have to do is save the record by clicking on the “Save” icon, as indicated.
When it comes to dealing with ? errors, you can simply edit the data in the record (arrow 2 below).
Alternatively, when you click on the data item, it is highlighted on the map (as in arrow 1 above) . You can then select it with your cursor and move it to your desired location. Most times, for these types of error, it’s easier to just review and edit the data. When you have corrected all the errors, make sure you save any changes.
Finally, if you want to add a new record, simply click Add Record and fill in all the data fields.
