[GIS] App for recording waypoints and photos for GIS on android

androidfield-mappingphotos

I'm looking to collect photos and notes during a field trip to add to (just for comparison) a landcover raster dataset I'm working with.

Ideally I want to visit certain field sites, take photos with my android phone, and afterwards be able to locate each photo on my map/GIS when I'm back home.

The standard location saving feature of the android camera isn't reliable enough.

I tried MapIt, which has a lot of features I don't need, but is costly. MapPad doesn't seem to permit exports into suitable formats.

You can try NextGIS Mobile. This application supports tracks recording, attaching photo and attributes to a new feature and much more. See instructions here:

Android Maps – Solution for Offline Map App

I did an offline map using the ESRI Android SDK and a custom tile layer. I used an ArcGIS server to generate a tile based map cache, then inserted those tiles into a SQLite database and query them based on row and column from there. It works great and if you need custom maps end to end, it is a very usable method.

package com.main.utilinspect;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.RandomAccessFile;
import java.util.List;

import org.codehaus.jackson.JsonFactory;

import com.esri.android.map.TiledServiceLayer;

public class OfflineDbTiledLayer extends TiledServiceLayer {

File workingDirectory;
String mapDefinition;
String databaseName;
private SQLiteDatabase database;
File blankImage;

byte[] blankImageBytes;

private final Object lock = new Object();


private static final String TAG = "OfflineTiledLayer";  


public OfflineDbTiledLayer(Context paramContext, File workingDirectory, String mapDefinition, String databaseName)  {
    super("required");
    this.workingDirectory = workingDirectory;
    this.mapDefinition = mapDefinition;
    this.databaseName = databaseName;

    String databasePath = workingDirectory.getAbsolutePath() + File.separator + databaseName;

    this.database = SQLiteDatabase.openDatabase(databasePath, null, SQLiteDatabase.NO_LOCALIZED_COLLATORS); 

    this.blankImage = new File(workingDirectory.getAbsolutePath() + File.separator + "blank.png");

    RandomAccessFile raFile = null;

    try {
        raFile = new RandomAccessFile(this.blankImage, "r");

        blankImageBytes = new byte[(int) raFile.length()];
        raFile.readFully(blankImageBytes);

    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block

    h1 = h.a(paramJsonParser, "test");
    }
    catch(Exception ex){

    }       


    setFullExtent(h1.f());

[GIS] Advanced android app for mapping and GPS logging

The Best is Sport Tracker (originally developed by Nokia)

enter image description here

Will log GPS data like coordinates, altitude, colour codes the route with GPS accuracy/number of satellites (optional)

Exports to GPX and KML (CSV and XML) Can view on the map or via Google Earth on Android (Ice Cream Sandwich - Android 4.0.3 works best) for this.

Available on Google Play (App Store for Android now) https://play.google.com/store/apps/details?id=com.stt.android&hl=en
