The program called Jeodezi (Geodesy), which my dear friend Behlül Numan ÖZDEMİR and I produced as part of our graduation project, has finally been released as version 2.0.1. I think it would be useful to share with you the work we presented last week. With the many calculation modules in the program, users can perform geodetic calculations precisely, easily and quickly, and the results can be saved or, if desired, printed.

In the program, shown in outline above, it is possible to calculate on different ellipsoids using the Settings tab on the right. All the modules in the program are listed in the table below.

Opening .KML Files in ArcGIS 9.3

In this video tutorial, which I prepared today in response to a reader’s question, I tried to explain, as the title suggests, how to open a previously created .kml file in the ArcMap interface of ArcGIS 9.3. Although it is a short video tutorial, I believe it also shows how to open many other file types besides .kml files with ArcGIS 9.3. I hope you find this content useful.

Note dated 06.08.2011: Because of the behaviour of many users acting solely in their own interests, the video tutorials have been placed under password protection. Perhaps this way the fact of how valuable knowledge is will regain its importance.

Save as WWF, Save a Tree

Thanks to the .wwf format introduced by the World Wide Fund for Nature (WWF), you can now save your documents in a way that prevents them from being printed. How? With a small program you install on your computer, you can save your documents in .wwf format just as if you were printing them, and then view them with any .pdf file viewer. While this aims to reduce paper consumption and protect trees, it also lets you protect, in digital form, documents you don’t want printed, such as articles, e-books and reports. To create .wwf documents, you can download the WWF software to your computer using the link below and thus make a contribution, however small, to protecting nature.

Finding a Lost Point

Stake-out, one of the main applications of us surveying engineers, is practised every year by KTÜ Surveying Engineering students in various ways. In this post I will share with you a PowerPoint presentation based on the topic of finding a lost point , one of the stake-out applications shown in the 2nd-year Geodetic Surveying course. In the presentation, to make it easier to understand, I tried as far as I could to explain the operations and calculations performed during the application dynamically and in order. Although I have shared the general structure of the presentation via SlideShare, I recommend that those who want to see the steps dynamically and in order download the presentation. I hope you find this content useful.

Coordinate Transformation in ArcGIS 9.3 and Exporting Data to Google Earth

This video tutorial tries to explain, in ArcGIS 9.3, coordinate transformation, an operation we surveyors use frequently; exporting data to Google Earth, now an indispensable part of daily life on our computers, in other words saving a .kmz file; and how point files saved in Excel are displayed in ArcGIS 9.3. I hope you find this content useful.
