Ingenious Symbol Editor.

01_pic_Symbole  

Even while OCAD provides you with many predefined sets of map symbols you might wish to create your own symbols.
OCAD has a powerful symbol editor which allows you to create any symbol you could imagine.

Each symbol can be edited, changed to a new icon, or simply hidden. To avoid unwanted changes in the map, symbols may also be protected.

Irregular Pattern Symbols. new

01_pic_Symbole   Representing area symbols (e.g. forest
or scree) with irregular patterns. Optionally
structure elements can be cut or
displayed completely at the border line.

Draw Perfect Curves With Bézier Curves.

02_pic_Bezier_Curve  

Drawing nice smooth curves like the ones defined by the courses of rivers, shorelines, or terrain shapes is difficult with popular drawing tools. To do this, OCAD offers the «Bézier curve» drawing tool. With it, you can draw perfect curves or bends quickly and accurately without any unsightly kinks.

No More Trouble With “Sliver Polygons”.

snapping

 

Drawing two areas exactly on top of each other or drawing a line or an area along an existing area is very difficult. Often, tiny gaps remain, which are called «sliver polygons» and interfere with the map image. OCAD offers you with the line tracing and the snapping functions to draw on existing lines very accurately or along areas without a single «slivering polygons».

You can find other helpful OCAD functions, like stairway and multiple point drawing, on the new OCAD online help: Drawing an Object

 

 

Influencing the Position of the Dashes of Dashed Lines.

03_pic_clear_intersection  

OCAD has a few unique drawing functions which ensure that your maps satisfy the highest demands on cartographical visualization. With the two functions called dashed vertex and corner vertex, you can influence the placement of the dashes or the dots of dashed or dotted lines.

Editing With OCAD: «Virtual Gap» and «Smoothing Lines».

06_pic_interpolate

 

OCAD introduces a new editing tool, the «virtual gap». Due to the use of basic Geodata, their geometry will not be destroyed. Therefore OCAD allows you to cut off a solid line to frame a contour number or a ditch in a contour line. Calculating contour lines from a DEM causes lines, which have lot of vertices. These have to be smoothening to look nicely. OCAD provides you with a smoothing tool, with which you can smooth the line all the way down to a straight line, if you want.

 

In Addition OCAD functions like reshape, crop objects, interpolate move and/or duplicate make map processing significant more efficient. A full list with those functions will be found on the new OCAD online help – the OCAD 12 Wiki – under «What is New».

Rubbersheeting – Georeference and Rectify Your Old Vector Maps.

05_pic_rubbersheeting  

With the OCAD Function Rubbersheeting Transformation, the generated map can be adjusted to a georeferenced template behind. Consequently you are able to rectify and georeference your old vector maps. In the OCAD-Online-Help – OCAD 12 Wiki – you find the «Rubbersheeting» instructions.

Calculations Out of Digital Elevation Model-Data With the DEM-Module.

07_pic_contour_hillshading  

Digital Terrain Models (DEM) is getting more affordable. This opens new prospects for cartography e.g. calculating hill shading or your own contour lines. OCAD supports XYZ- or grid formats to import DEM or LiDAR into OCAD. The DEM-Module has been enhanced to enable the use of new data sources such as hgt (height data from the Space Shuttle mission) and LAS (laser airborne scanning). Moreover there are new analytic tools which derive vegetation height classification and slope maps.

Step-by-Step-Wizardnew for DEM.

 

LiDAR and DEM data are getting more and more important to create topographic maps. A step-by-step wizardnew helps you to analyze them and creating hill shadings, contour lines, cliffs and vegetation height maps. Moreover you can lay profiles to analyze intermediate LiDAR impulses.
