3. Working with layers
|
Layer types There are several layer types available in Field-Map. Point, line, polygon and data are the basic layers. Tree, deadwood, transect, connection and half connection are more complex layers specific to Field-Map. Point – a layer describing entities which may be simplified into points, such as soil sample points, bird nests or observation points. Line – this layer describes linear features of the landscape, such as borders, water streams, paths or roads. Polygon – describes areas with unique values, such as forests, water bodies or urban areas. Data – the only non-geographic layer; contains attributes such as owner description or weather conditions. Tree – this layer is derived from points with extended functionality. It describes trees. Deadwood – describes deadwood such as fallen or uprooted trees or woody debris. It is also more complex. Transect – a line crossing the plot. It is used to visualize a vertical terrain profile and vertical tree crown profiles. Connection - map symbols of the “S“ or “Z” shape marking two neighboring areas pertaining to the same polygon. Half connection - map symbols of the “S“ or “Z” shape cut in half marking two separated parts of the same polygon. Polygon store - allows creating overlapping polygons that can serve as a quick field sketch layer.
