Java File Geodatabase (FGDB) JNI Wrapper, permit to read/write simple features in .gdb from Java

jfgdb - Java File Geodatabase thin driver

FileGeodatabase (GDB) is a very efficient file format for storing GIS Data.

This package provide a java library wrapper and ESRI FileGeodatabaseAPI (1.4) embedding to a simple use on java.

This project bring a fast READ / WRITE of simple featureclasses for Java environment.

More informations on the FileGeodatabase API, supported plateform, can be found

https://github.com/Esri/file-geodatabase-api

Using this library, you MUST agree to the ESRI (inc), FileGeodatabase License conditions :

Additional FileGeodatabase API usage conditions are explained here : https://blogs.esri.com/esri/arcgis/2010/12/13/file-geodatabase-api-details/

Usage

This library has been compiled and tested on some Windows X64/x86, Linux x64. Extensive plateform tests could be done by the community.

Binaries are included for the windows plateform, for ease of use. Compilation on other plateforms are one command line far.

Binaries are also included in the jar file for moderns x64 Linux. Due to OS dependencies loading (dlopen primitive), see this note before running the jar.

set JAVA_HOME=[YOUR_PATH_TO_JDK1.7_OR_UP]
set ESRI_FILE_GDB_HOME=[YOUR_PATH_TO_ESRIFGB1.3ROOTDIRECTORY]
gradlew build -x test distZip

but i check the floder " /tmp/fgdbsharedlibs/0.1.4",it's existd.
thanks.

Binary / Blob support,

Hi Patrice,

I'm using your Java File Geodatabase wrapper to read geodatabases and ran into an issue. There are some blob fields I'm trying to read out but it doesn't seem there are methods to do this via your wrapper. When reading through the documentation for the API it looks like there is a method row.getBinary that will return a byte array field, which seems like it could work to read the blobs.

Is there a reason the Java wrapper doesn't have this method?

Or, if I'm missing something, is there a way to read out the blob fields?

Thanks,
Jenna

The error "unrecognized command line option "-m32"" in ARM

Hi, We really like this library and use it on different platforms. When we compiled it on ARM architecture, the following error occurred: g++: error: unrecognized command line option '-m32'. We checked the error and unfortunately found that the -m compilation parameter of Arm gcc/g++ does not support 32-bit or 64-bit. So how do we solve this problem? Thank you
