Re: [GRASS-dev] GSOC project proposal: GUI plugin system for GRASS GIS
Hello, Sorry for the late reply. I was busy with exams last week. I compiled the code from source, read a tutorial on grass gis and I am fairly comfortable with grass environment. I was looking into the Bug: Quotes not preserved in command after pressing enter in GUI command console and tried it out on my machine. I was trying to fix it and I think most probably it's some problem with regex search which is deleting the quotes from the command. I was looking into the code for fixing the bug but couldn't find the relevant file to change. Could you please guide me with that. Also for the enhancement: Button, documentation and perhaps something more interactive for finding EPSG codes online rather then in GRASS GIS list I was thinking of more interactive process of using EPSG - 1. We can merge epsg.io code into our existing structure. http://epsg.io/ 2. We can add a button that will redirect users to epsg.io I would like to have your suggestions on the same I know I am running a bit late with the bug fixing but I can assure you I won't disappoint you during the course of project. I am very interested in doing GSOC under grass org as it will be an added advantage to my ongoing research in computer science and spatial informatics. I would be thankful if you could help me with submitting GSOC proposal. Regards Jyoti On Thu, Mar 12, 2015 at 9:10 AM, Vaclav Petras wenzesl...@gmail.com wrote: Hello.

Just keep in mind that this GSoC project would be in Python and wxPython. You can attempt to solve more of these tasks, the more the better. In any case, the thing you select and do should be in Python and should sufficiently represent your skills. Draft implementation of non-GUI (model) part of the plugin system would be helpful to understand the issues which you should address in the application. In any case, start with compiling GRASS GIS from source code (trunk) from Subversion repository [4], reading tips for students [5] and going through instructions for other students [6, 7] (you can use Nabble [8] for that). Also read Submitting rules [9] and how-to [10] for wxGUI development. Also learn how to do basic tasks in GRASS GIS graphical user interface (called wxGUI), use e.g. GRASS wiki or the manual as learning resource.

Re: [GRASS-dev] GSOC project proposal: GUI plugin system for GRASS GIS
I was looking into the files you sent and I think I am going in the right direction. I will try to complete the task as soon as possible. As for the enhancement I was thinking of creating a search box in our current structure that takes the users query and redirects it to the result page of espg.io with the query. For e.g. if I search India redirect URL will be http://epsg.io/?q=india. But where exactly do I need to make the changes? Please help me with that.

Regarding Bug : Quotes not preserved in command after pressing enter in GUI command console My idea: - Find the code which is taking command as input and passing it to RunCommand function. - Most probably error is in reading the input from stdin and storing it in variable. - Code might be running some regex search(or something similar) to remove everything expect alphanumeric characters from the command string. - My approach to fix this bug is to find that point and study for the cause of error and fix it. Regarding enhancements to add epsg code : My idea as described earlier : - Add a button and a text box to the current implementation of wizard.py which will take location as an input and redirect the user to epsg.io with the url epsg.io/?q=location . - This is will require to read the input from the user and appending it to epsg.io URL. - User can then select among the different search results on the espg.io page he is redirected to. But with both tasks I am getting same problem, the code is very big and there are many files to look into, and I'm not able to find the exact place to do the corrections/enhancements. I know what to do in both situations but lack the complete and exact knowledge of GRASS code structure. Can you please guide me to the exact line of code where the changes have to be made. Sorry, I cannot do that. If I would know where (and how) to fix it I would already do that. You must understand that although now this serves as an exercise for GSoC, it is a real issue which is in GRASS. Also, for the GSoC you will need to understand the existing code to certain extended to be able to incorporate your code and to fix the bugs which can emerge in both new and existing code.

I am interested in working with grass org under the project New easy-to-use command line interface for GRASS GIS*. *The problem looks interesting to me. I am familiar with the technologies needed for this project.As i have already worked in c++ and python . Hi, this sounds good. You should find some enhancement or bug in GRASS GIS bug tracker [1] and implement or fix before the application evaluation it to show level of you proficiency [2, 3]. For example an enhancement ticket #1204 related to invoking GRASS. The wish is to start grass7 command with a wxGUI workspace file as a parameter [4]. Another option is to continue in implementing of related #2579, enhancement to provide command line parameter to execute modules. However, the big issue there is more the discussion about the interface rather then the implementation itself which is partially done already. More challenging option is to implement some part of the GSoC project, e.g. for rasters or for PostGIS vectors. This is of course highly related task but it can be tricky and what you need is something which is working well before the application evaluation. More smaller tasks might a better idea. To understand how projections (coordinate systems) work in GRASS GIS (see below), it might be advantageous for you to implement r3.proj module which would project 3D rasters from one GRASS Location to another. r.proj module is in C but for start r3.proj module could be in Python and would use r.proj in the background (similar idea can be ussed for GRASS imagery groups and temporal datasets which also don't have their proj module). Further, you could try to write r3.in.proj module which would import 3D raster data in one projection to GRASS Database with another projection (see source code of r.in.proj). See below for more resources on this topic. Writing tests for related things such as #2579, or modules r.in.proj, v.in.proj or the other modules mentioned below might be quite good introduction to the topic but to show your skill you might want to combine it with some other task which would involve actual coding. However, you can explore the open issues on GRASS GIS bug tracker yourself. Just keep in mind that this GSoC project would be in Python, so the thing you select be in Python. In any case, start with compiling GRASS GIS from source code from Subversion repository [6].

Start with running GRASS GIS and playing with data in different projections in case you are not familiar with GRASS GIS already. Read through the related manual page [7] and/or tutorials online on getting your data into GRASS Database. Definitively read the code from various projects and other things linked in the GSoC idea [8]. Go through the modules related to importing, linking, exporting and projecting data, some of them are linked below. Look also at how GRASS GIS can connect to PostGIS [9].
