In number of emails I have been asked how to create an offline map from geo-referenced image. Please follow this article to create .mbtiles file ready to use with MapIt from an image. We use open source software to achieve the goal.
Maperitive software to generate the .mbtiles file.
Please follow the steps below to get the offline map of Kilimanjaro in format compatible with MapIt:
1. Open qGIS and open a Georeferencer plugin as shown below:
2. Add your image to the plugin and set the spatial reference – you can use filter typing 4326 in the filter box.
3. Selecting georeferencing points.
Depending from the type of image you may use 4 or more points to georeference an image.
Zoom to the upper right corner and add point then enter longitude and latitude of that location:
Add another 3 points. Please make sure, that your working diagonally. In our example it would be: upper left, lower right, upper right, lower left. This will minimize problems according to the visibility of the map during georeferencing it.
4. Transformation settings
Before we georeference the image please go to Settings and set Transformation settings as shown on the picture below:
5. Georeference the image and add it to qGIS map view to check out if everything is fine. Go to the used crossings of longitudes and latitudes and compare the shown coordinates with the desired coordinates. If they fit, you are done and ready for next step.
6. Before we use the image in Maperitive we need to convert the wld file (created during the georeference process above in the same location as the image) to georef file used by Maperitive.
Make sure that the number of decimal digits for the cell size is not>17 in georef file, otherwise Maperitive will complain.
Hi, It’s been a while since I have posted anything. Just to let you know that MapPad project has grown significantly in the past year, lots of new functions have been added and you can get the app demo for free here.
The most recent update includes WMS and ArcGIS Server Tiled services support, you can add your own Google Maps overlay and improve your productivity even more:
Hi guys, check it out – it’s my first app for android devices. I am looking for some comments and feedback, if you work in real estate, forestry, agriculture business – it’s going to help you out. At the moment English, Polish , Portuguese and Italian localisations are available.
I am looking forward to include other languages and need people who can speak particularly Spanish, Chinese, Russian – whatever :).
In the past week I came acros a problem of displaying X,Y event based on quite complicated, multitables, multiowners query.
Usually I work with Oracle database, however this time I had to pull out the data from SQL Server database.
I have created sucessfully the View, and served the X,Y data as the MapService through the ArcGIS Server – everything was fine until I had to relate another table and the problems jumped out as there was no OBJECTID field presented in the view.
"Index cannot be created on view '....View_Ix' because the underlying object '...._origin' has a different owner." – that was probably because I had several tables from different users in my query, anyway…
After few hours of checking diferent things I have discovered that if you use the “Make Query Table” tool from ArcToolBox before you make your XY event layer and specifiy which field to use as a key in that tool, it works just great.
I need to test few things yet – so check if the data is being updated properly in that new table etc, but at the moment everything looks promissing.
I hope that hint will be useful for some of you as well.
