Fix clipping issues by using limito and refactor some code (#87)
* Fix import error due to differences in geom type * fix id missing in clip table and skipping importing shapefiles with geometry errors * fix clip id error in the sql * Change postgresql version from 9.6 to 11 * Added sql to validate geometry and other make commands to run them manually * added pgwatch to docker-compose * Modified importer.py to import clip file if it exists and changed logic for finding if tables are missing * updated readme file * fix logic on first run for importing data * small changes to revert original logic * remove clip functions since they are not needed because of the limitto function * Added logic to check if the geojson should be used if it exist or not, added martin to server vector tiles from the DB * update readmepull/63/merge

### Clipping
|
||||
|
||||
You can put a shapefile in the clip folder. This shapefile will be
|
||||
used for clipping every features after the import.
|
||||
This file has to be named 'clip.shp' and in the CRS you are using in the database (4326 by default).
|
||||
When the database container is running, import the shapefile in the database using the command :
|
||||
During the initial import or post update imposm uses the flag `-limito` which allows
|
||||
you to define a smaller area that you can work with.
|
||||
This is always desirable to limit the features being imported into the database rather
|
||||
than clipping them.
|
||||
|
||||
`make import_clip`.
|
||||
**NB:** Ensure you add a geojson covering the area you intent to clip into the settings folder.
|
||||
The geojson can be the same extent of the administrative area of your country or it can be a
|
||||
smaller extent. The CRS of the geojson should always be EPSG:4326.
|
||||
|
||||
You can remove the clip file : `make remove_clip`.
|
||||
|
||||
**NB:** It is encouraged to simplify the geometry for the `clip.geojson` as
|
||||
a simplified geometry is easier to process during the import.
|
||||
Rather use the minimum bounding box for the area you intent to clip your dataset with.
