ESRI file geodatabase to PostGIS converter

Project description

The aim of this tool is to convert an ESRI file Geodatabase to a PostGIS database maintaining data, domains, subtypes and relationships. The tool will copy over the feature classes as postgis layers and the tables as standard tables. The domains and subtypes will be converted to PostgreSQL lookup tables. The tool will then create all necessary indexes and constraints to maintain the required relates between the layers, tables and lookup tables. To recreate the same experience of the domains and subtypes in QGIS using the output data, please install the plugin Data Manager. Now you can have domain experience in QGIS that is stored in the database and not in the QGIS project.

Note

This library requires GDAL/OGR libraries and ESRI ArcGIS Pro to be installed.

Installation

This package should be installed on windows systems into ArcGIS Pro conda python environment. (because of Arcpy)

Install required packages::
  • pip install numpy>=1.12.0
  • pip install psycopg2>=2.6.2
  • pip install ruamel.yaml>=0.15.35
  • pip install awesome-slugify==1.6.5
Install fgdb2postgis::
  • pip install fgdb2postgis

Note

  • This tool requires to have GDAL/OGR libraries and ArcGIS 10.3 or later installed.
  • ESRI Python packages usually under C:Python27ArcGIS10.* might not have pip included make sure to
    • Install Anaconda/Miniconda
    • Install pip if not already installed
    • Setup ESRI python and GDAL/OGR in windows path environment variable
  • Activate python environment
    • activate C:\Users\<user>\AppData\Local\ESRI\conda\envs\<esri-py>

Usage

Create a yaml file mapping the file geodatabase’s feature datasets, feature classes and tables to postgresql’s schemas. It is required that the yaml file have the same name with the file geodatabase with the extension .yaml If the yaml file does not exist it will be created automatically, splitting the file geodatabase feature datasets to postgresql schemas Since we have the yaml file with the entire schema of the file geodatabase we can modified it and run the tool again.

Example:

filegdb: sample.gdb
   yaml: sample.gdb.yml

Note

The yaml file should be located in the same folder and having the same name as the file geodatabase. If the yaml file does not exist it will be created by inspecting the file geodatabase and converting the feature datasets into schemas. The schema lookup_tables will always be created regardless of the yaml file.

Yaml file example:

Schemas:
  - Administrative
  - Epidemiology
  - Radioactivity
  - Seismic
FeatureDatasets:
  Epidemiology:
    - Epidemiology
  Radioactivity:
    - Radioactivity
  Seismic:
    - Seismic
FeatureClasses:
  Administrative:
    - sectors
    - governorates
    - sub_sectors
Tables:
  Epidemiology:
    - EpidemiologyTS
    - EpidemiologyTST
  Radioactivity:
    - RadiationTS
    - RadiationTST
  Seismic:
    - EarthquakeTS
    - SeismicTST
Schemas:
The schemas to be created in the target postgis database.
FeatureDatasets:
Mapping of the geodatabase’s feature datasets to the schemas of the target postgis database
FeatureClasses:
Mapping of the geodatabase’s feature classes that do not belong to any feature dataset to the schemas of the target postgis database
Tables:
Mapping of the geodatabase’s tables to the schemas of target postgis database

Command line options:

fgdb2postgis -h
fgdb2postgis -f filegdb
            -p postgis
            --host=host
            --port=port
            --user=user
            --password=password
            --a_srs=a_srs
            --t_srs=t_srs

Tip

  • This tool is tested with:
    • GDAL/OGR v 1.11.4
    • PostgreSQL v 11.7
    • PostGIS v 2.5
    • ArcGIS Pro v 2.5.1
  • The tool supports only Latin characters for field names and suptypes while domain values and descriptions might be in any locale.

Warning

  • DO NOT apply this tool in a production postgis database!
  • The target postgis database should exists and be EMPTY.
  • The tool will OVERWRITE any tables having the same name with the tables in the file geodatabase.
Last Update:
  • Migrate to Python 3.6.9 (ArcGIS Pro 2.5.1)
  • 12 May 2020
