Validating scanner profiles
The comparisons revealed that the ALS based profiles of sea level heights agree reasonably with the regional geoid model (within accuracy of the ALS data and after applying corrections due to sea level variations).Thus ALS measurements are suitable for measuring sea surface heights and validating marine geoid models.Mostly the ALS is used to measure terrain surfaces for compilation of Digital Elevation Models but it can also be used in other applications.This contribution focuses on usage of ALS system for measuring sea surface heights and validating gravimetric geoid models over marine areas.It’s easy to create well-maintained, Markdown or rich text documentation alongside your code.Sign up for free See pricing for teams and enterprises Retro Pie allows you to turn your Raspberry Pi or PC into a retro-gaming machine.In fact, no matter what I enter, only the else statement is entered. How can I fix it Here's the original function code: While you're helping (I'm going to search but if I don't find it) what's the best way to recognize blank input in a scanner object?
A network TWAIN driver will still be required for the MFP to scan to TWAIN-compliant software applications.
A test area at the southern shores of the Gulf of Finland was selected for regional geoid validation.
ALS measurements were carried out by the Estonian Land Board in spring 2013 at different altitudes and using different scan rates.
The one wavelength Leica ALS50-II laser scanner on board of a small aircraft was used to determine the sea level (with respect to the GRS80 reference ellipsoid), which follows roughly the equipotential surface of the Earth's gravity field.
For the validation a high-resolution (1'x2') regional gravimetric GRAV-GEOID2011 model was used.
