GIS raster reclassification inventory calculator

Calculate output class and total count and unmapped value counts with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use output class and total count and unmapped value counts to compare changes to your inputs. The method and limits below explain the scope.

Examples

Examples

Try the starting example

Value frequency rows [value,count]
[[1,10],[2,20],[3,5]]
Mapping rows [input value,output class]
[[1,10],[2,10]]
Output class and total count
[[10,30]]
Unmapped value counts
[[3,5]]

Try another scenario

Value frequency rows [value,count]
[[1,10],[2,20],[3,5]]
Mapping rows [input value,output class]
[[1,10],[2,10],[3,20]]
Output class and total count
[[10,30],[20,5]]
Unmapped value counts
[]
Calculation method

Calculation method

Output class and total count

Map exact values; sum frequencies by class.

Unmapped value counts

Values missing from mapping stay explicitly unmapped.

Symbols and units
a
Value frequency rows [value,count]
b
Mapping rows [input value,output class]

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • Value frequencies, supplied mapping rules. Returns Output-class counts and unmapped values. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification.
Are these inputs private?

These calculations run in your browser. A shared link contains the values you choose to share. Only questions submitted to the separate AI finder are sent to OpenAI.
