The term “spatial data” used to describe any data related to or containing information about specific locations on the earth’s surface. Hence, many of the field data you collected can be considered as spatial field data. Spatial field data collection involves collecting three types of features, namely points, lines, and polygons.

Why is geospatial information sensitive?
Geospatial information is inherently sensitive because it is tied to specific locations and people. When building applications that collect or share personal information, it is important to consider whether the people who are being represented know that their information is being used and how it is being used. Privacy of information laws must be considered. (To read more about the ethical implications of mapping, see Crampton, 2010.)

How does remote sensing work?
These signals are then transmitted to receiving stations on Earth where they can be transformed and distributed as digital images to be analyzed. Through the use of remote sensing, applying specific calculations to images can help spatial information analyst identify and classify features on a landscape such as changes in snowmelt and identifying the location of seasponges [1] without physically setting foot in that region. Remote sensing can be used to sense changes in ground cover, locate the presence of surficial minerals and identify the location of different types of vegetation. Both the Government of British Columbia [2] and the Government of Canada [3] extensively utilize remote sensing.

Why is FME important in GIS?
While there are many tools and software that can help you make use of spatial data, FME is the software of choice for those that need to integrate their spatial data. Safe Software and FME came into existence because of this exact problem. Spatial data varies widely and is often stuck in formats that cannot be easily used by all applications, making it extremely difficult for GIS experts to make use of all the information they have. While it was possible to transform proprietary formats in the past, much of the data would be lost in the conversion. Thus, FME was born.
