Transectizer 2.1: Scrollbars and GUI updates

Transectizer is a QGIS plugin which provides an easy way to design linear transects with sampling stations distributed at a given distance along the transect.

Transectizer makes possible to automatically generate each individual station details (transect name, station name, station number) or have control over all the attributes of each station.

You can store your transects in a new layer or provide an existing layer for it. In that case, Transectizer will make the appropiate changes to your layer to make it compatible with Transectizer.

This releasex fixes a problem which made not possible to show scrollbars when the dialgog was resized plus some minor GUI enhancements.

The basic operation of Transectizer is pretty simple: You choose a point layer to operate, define your transect line, set the distance between the stations to be deployed and the number of them and that's all... Transectizer will add each station as a new feature into your layer.

You can find detailed information in the plugin's web page at:

Transectizer positions the stations using Vincenty's direct formula, using the WGS84 ellipsoid to perform the calculations. They are made feeding Vincenty's formula with the same inital point but different destination distances. These distances are the n-multiples of the the distance between stations, being n the number of the station to be deployed. But another approach could be to fix the distance but move the point for calculation: First point should be the start point, second point is calculated from first, third from the second, and so on. Providing that these two approaches render different results, if you feel that either the calculation proceeding I've chosen is wrong or you think that the two methods should be available for the user to choose, please contact me. I'll be glad to modify Transectizer in the best possible way.
