[uncertainty] In GIS, a state of uncertainty in data classification that exists when an object may appropriately be assigned two or more values for a given attribute.

 


Carrier phase positioning for safety of life critical applications requires an extremely reliable integer ambiguity resolution.

ambiguity resolution
with carrier-phase observations, the number of carrier-phase cycles between the receiver and the satellite is generally unknown and is referred to as the ambiguity and is an integer number.

Semantic ambiguity exists when different meanings are associated with the same term (polysemy), or when different terms mean the same thing (synonymy).

To avoid ambiguity, DEM will be used exclusively for a grid framework, so it can be read matrix. derived measurement p.

At heart, these debates arise out of the ambiguity of GIS as a tool and GIS as science.

The operations can be performed in any order, and the parentheses may be omitted without ambiguity (i.e. either of the above can be expressed equivalently as A ∪ B ∪ C). Similarly, union is commutative, so the sets can be written in any order.

Also, the robustness of OGC specifications sometimes leads to ambiguity in implementation, even among OGC-compliant products.

This way, there is no ambiguity and minimal changes are needed. But the MP 4 is no more the end of segment 3 - 4 but the end of segment 3+2000 - 3+3000. This information must be entered to the system and it is done by optional MP attributes: ...

As an example of the inherent complexity of this ambiguity, Sir George Harrison (Attorney General to the Duchy of Cornwall) during the Crown-v-Duchy Foreshore dispute of 1858 described Cornwall as "A palatine state, ...

Consistently using a tested and approved set of conversion guidelines and procedures will eliminate any chance of ambiguity in methods. Using established procedures will allow for the most consistent product possible.

the raster GIS program you have, determine how that program uses (a) the concept of "zone" as a contiguous group of cells of the same value, and (b) the concept of several groups of cells that all have the same value. Is there any ambiguity ...

a theme - for example, 'Stamford Ware' within the pottery theme or 'Hillforts' in the Iron Age site theme. In order to avoid confusion, it is important that the names given to such themes and layers are both descriptive and free from ambiguity.
