Geocode addresses: Different cases

The coordinates of the addresses are displayed almost positionally accurate on a 100m grid (Inspire 100 m ETRS-LAEA grid) due to the included geocoding from EasyMap 11.2 on. Thus, addresses that are close together can fall on the same grid coordinate, so that symbols could overlap. If you need a precise positioning, our additional function easymap office pro and the LTGeoCoder is available.

Here we show you the reasons why addresses are not found or not placed correctly and how you should enter your data to avoid this. More on the topic Coding addresses geocoded can be found in the chapter Calculations.

Address was geocoded, but no symbol is displayed

Placement via addresses behaves differently than placement via area numbers. For more information on placement, please refer to the chapter Level and Assignment.

 

On the following picture the placement on the map via area number is compared with the placement via address:

Placement by area number (orange) gives us points on the map that were placed one above the other in the center of gravity of the postal area, while placement by address gives us points (green) that were placed on a specific street and are better distributed on the map. This makes it easier to see the location of the data on the map.

Note: If no house number is specified, any address on this street is selected.

Addresses were not geocoded: Blank lines

The newly created column for the geocoded address can now contain empty lines. This indicates that the specific address could not be found.

You can find the records that could not be geocoded either by searching for the rows with the exclamation mark or by setting a filter to empty cells in the column with the geocoded addresses. In this way, only addresses that could not be geocoded are displayed.

Addresses were geocoded correctly, but not placed correctly on the map

In all cases a similarity comparison is carried out. Thus it is not excluded that a city or street with a similar name is found for the determination of the coordinate if no exact match could be found before.

 

Note: If no street is specified in the placement via address, easymap will place a point anywhere in the place found.

Preparation of the data for a correct geocoding

The more address components are specified in the formatting, the more precisely the coordinate can be determined. We therefore recommend that you include as much information as possible about the location in your tables, especially the street, house number and postal code.

If possible, enter the complete address, postal code and city and use this information to create a table similar to the one shown in the image. To increase the chances of success of one of the codes, please do not use any special characters or abbreviations.
