Koorachund Mapping Exercise 2.0

Advertisements – A Social Network based on Quiz

New Web application for quizzing-

We’ve been observing an increasing number of people in facebook who make and join groups to ask GK questions for information sharing and fun. But facebook group is not built for quizzing and the whole fun of finding the answer remains until the first guy finds and posts is as comment. QuizGrid essentially solves this problem, answering and commenting on a question are different entities in QuizGrid. Also the support for questions with options is another advantage among many other features in this quizzing platform.

As usual he has done a great job. He is none other than my Dearest fellow- Ershad Kunnakkadan. (blogpost by him on this)

This is my gift to him- a boy who is truly dedicated.

Map making with Inkscape and Google Earth

Preparing a professional vector map using Inkscape


As part of a project, I was in need of the map of the area. I went to panchayath office and village office, but the result was negative. The map which they gave and the format was not useful for me. Thus I decided to prepare it using Softwares. I installed Qgis and Google earth. Qgis was heavy for me to study in limited time. Also the lack of high resolution image from google earth (google earth’s pro can give you) resulted in my failure. But I was to not ready to gave up. I thought of alternate way and ended up in inkscape (the one which I know) I have described the way i have done it.

I am thankful to my sir George Basil (IIT Delhi), Manoj K Mohan, Jaisen Nedumpala for their help and advices.

I strongly recommend you use a GIS software for greater accuracy and easiness.

Steps :

1. Obtain a screen shot of the required area from google earth file > Save As…

2. Open inkscape import the image file > import

3. Create layers Layer > Add layer / (shift+ctrl+L)

Adding a layer

4. Lock the basic layer with our image by clicking the lock symbol i the side dialogue box

5.  Use Bezier Curve tool to Trace the areas like land, pond etc. Use Node tool to adjust if neded. Adjust colour and opacity)

6. Lock the layer and add another layer. Say “Water”. Use Calligraphy Tool for tracing roads and rivers. It is preferred to have some tremor for rivers and streams. and for Roads adjusting the width can indicate different types of roads.

7. After all layer is traced, off the other layer to get the needed layer. From this use can get an individual map for roads, rivers, land area, and others if you use the layer function effectively.





Nb: Use of drawing aids can give you more accuracy.

8.  Index the map using text tool.

Malayalam fonts and problems with inkscape

Posted on

This is my first blog post on a technical subject. Hence it may have its own deficency. First let me thank my buddy ERSHAD.K (as he is the soul reason behind the publishing of this post), SMC, HIRAN VENUGOPAL(developer of DYUTHI.ttf), and the software fontforge, inkscape.

The situation which made me to publish such a blog is the overlapping of certain malayalam fonts in inkscape, whereas some other fonts (like anjalioldlipi, dyuthi). When there occured a situation for me to use stylish malayalam fonts in inkscape.

overlapped text in meera font

 Atlast I decided search the reason for this. . .
I was using Mozhi And Swanalekha for rendering malayalam. I thought it may be the problem with the lack of cordination between inkscape and those softwares. Hence I studied inscript pattern. Still there was no use. No matter how you render the letters will be overlapped(only for those fonts with probs). Hence I opened the fonts in fontforge. Fonts like anjalioldlipi, dyuthi etc. has drawn letters under each unicode both in english and malayalam. But the other fonts haven’t provided drawings of letters in both.

dyuthi opened in fontfroge

anjali old lipi opened in fontforge

Most of them have given drawings of malayalam letters in english the place of english letters viz, A=or in some other ways.

When I render the English alphabets in those fonts the corresponding malayalam letters are apperaing. Hence i concluded the problem with those fonts. But agian the font Meera which had given drawings in both English alphabets and malayalm alphabets overlaps in inkscape, for which I dont have an answer for you.


PS: Anyone knows the reason behind this or my reason behind this is wrong please tell me.

ചുവന്ന രക്തന നക്ഷത്രം !

43 വര്‍ഷം മുമ്പ് തന്റെ രക്തം കൊണ്ട് ഒക്ടോബര്‍ 9നെ ചുവപ്പിച്ച വിപ്ലവ ഇതിഹാസം ചെ ഗുവേരയെ

ചെ | Che Guevara (drawn by me)

നാമാരും മറന്നിട്ടുണ്ടാവില്ല. എന്നിരുന്നാലും ആ വീര ഇതിഹാസത്തെ ഞാന്‍ ഒന്നു കൂടി സ്മരിക്കുന്നു..
