1. Hemisphere UTM Zone Mandatory Mandatory Output will be given at the J and K columns CREATING DXF FILE USING AUTOCAD First thing to be noted is that the block elements in a dxf file will not be converted during transformation So it is recommended to explode all those block elements before saving it as dxf file When exploded the elements constituting a block will get separated and MapEarth2D will be able to detect ad process it To save as dxf file use the save as option in AutoCAD and select dxf many dxf options will be there chose any GEO REFERENCING A DRAWING IN AUTOCAD A drawing has to be geo referenced if we are using the dxf file for making a drawing in Google earth MapEarth2D offers two modes Direct Mapping and Compensated Mapping for this conversion and hence the drawing has to be set in two different ways for the respective modes of operation SETTING FILES FOR DIRECT MAPPING MODE In direct mapping mode the co ordinates in a drawing will be directly mapped to different formats In such a case it is advised to make the drawing confirm to the actual coordinate limits when converting to Google Earth files This can be made by comparing the drawing with anticipated location of that drawing in Google Earth If the coordinates are outside the expected limit then unexpected results will be the outcome Steps involved in geo referencing an existing drawing 1 Get 4 coordinates from Google earth i2.

3. from Google earth which corresponds to a particular point say X in the drawing 2 Move the drawing to this point in such a way that the point X in drawing is at that point Now the drawing is geo referenced as far as the compensated mapping is concerned Only thing is that the point to which the drawing is moved is to be mentioned in the reference longitude and latitude fields The entities in drawing which are too far Around 3000kms away from the reference point may appear distorted Since such drawings are very rare Compensated Mapping fairs relatively well in all day to day works and drawings with such large spans has to be made with direct mapping method CREATING KML KMZ FILES USING GOOGLE EARTH This process is pretty straight forward when using Google earth as the files created from it will be geo referenced by default CREATING XLS XLSX FILES All files made in Microsoft Excel are either saved as xls xlsx file The only thing to be taken care of when using such a file in MapEarth2D is the formatting MapEarth2D will process your files based on a fixed formatting If the format changes unexpected errors will occur Setting Formatting of xls xlsx files for conversion is already mentioned in section EXCEL FORMATS FOR TRANSFORM MODE and EXCEL FORMATS FOR TWEAK MODE CREATING A GPX FILE Easiest way to make a gpx file is to use the MapSource software This package comes with Garmin GPS or it can also be downloaded

5. issues The sections are divided based on different modes of operation of software Each section will have details about usage of all the features and precautions to be taken on using those features along with other details GENERAL When creating a file for use with MapEarth2D it is recommended to make a copy of the original file and use that copy in the software Certain features in the original document is to be deleted before processing it with MapEarth2D and using the copy of original for this purpose will help in preserving the original work A brief description regarding various file creation handling methods are given here before going to the functional descriptions of MapEarth2D In all 3 modes when a file is uploaded you can see the components in that file in a window with a checkbox near each of the components The features to be processed in MapEarth2D can be isolated by selecting the check boxes QUICK REFERENCES ADDING EXTRACT MODULE TO MAPEARTH2D Step 1 Install and open MapEarth2D Step 2 Go to Tools gt Plugin to open the Plugins window Step 3 Go to Downloaded tab Click Add plugins to add downloaded plugins Extract Module in to the plugins manager Step 4 Select the checkbox near the plugin and press Install button at the bottom Step 5 Answer various dialog boxes appropriately and click Finish Note The plugin may be unsigned don t panic Install it if you have downloaded it from www mapearth2d com

8. k has a certain type of output and it is given as a dropdown in the control section Coordinate tweaks will help in transforming one coordinate system to another in excel The input has to follow the same format as mentioned in general section if the input is not in UTM If input is in UTM the input values has to be placed in columns F G H and filled with Hemisphere N or S zone easting and northing respectively Also the output generated will be placed in F G H and if the output system is UTM and it will be placed in J and K if output system is any other kml tweaks provide facilities to name turning points in a path with multiple turning points Part1 of this will be repeated in every names and an optional Part2 will be added to Part1 if 0 9 99 option is chosen If Part1 is put as A and Part2 is selected as 0 9 99 then the points will be named like A1 A2 A3 till the last turning point If multiple lines are selected all will be numbered continuously Other kml tweaks involve creating shapes such as circles and ellipses The values like radius major axis minor axis etc are to be given as inputs and the file to be uploaded should be in kml kmz format Based on the coordinates the specified shape is created for given values of input Reversal of a particular line direction is also a feature included in kml tweaks An uploaded kml file is reversed just by the click of a button For area measurement only thing to be given as i
9. n decimal degrees inside which the drawing is to be mapped 2 Draw lines connecting these points in AutoCAD to make a quadrilateral Scale the existing drawing appropriately to make the size of the drawing such that the drawing will fit within the quadrilateral Move the drawing to quadrilateral and now the drawing is geo referenced 5 Convert the drawing using MapEarth2D and see how good it fits to your plans If required you may adjust the image more to make it fit better Usually this process is tedious as the drawing has to be scaled down too much to fit it in the actual geographic coordinates The geographic coordinates are actually on a spherical surface and coordinates in AutoCAD are on planar surface A unit change in a geographical coordinate will map to changes in the order of kilometres on AutoCAD So a drawing made to match the geographical coordinates will appear to be too small compared to normal drawings created in AUtoCAD SETTING FILES FOR COMPENSATED MAPPING MODE In Compensated mapping the distance between different points is preserved Distance here means the distance between two points in metres irrespective of its units specified in AutoCAD For example if the magnitude of a side is 40 and the author has set the units to millimetre but MapEarth2D will take it as 40metres User has to take care of this fact Steps involved in geo referencing an existing drawing 1 Geta point Longitude Latitude in decimal degrees
10. nput is the kml kmz file which has the entities whose area is to be measured The measured area in metre and perimeter in metres will be shown in the table at the bottom of the control section Of all the selected entities only the first 100 entities values will be shown in the table MODE 3 EXTRACT This mode helps in extracting values of elevation at predefined points or at predefined intervals along a line The line or points can be given as a kml kmz file and the interval at which the values are to be extracted can be given in the specified field in control area A good internet connection is preferred while this mode is in operation as there is a daily restriction by Google on the number of values that can be extracted from Google Earth An error in connection may force the system to query the same values multiple times and thus wasting queries The output from Extract mode will be in Excel format with the first 2 rows left blank for internal purposes of the software
