AnswerFactory Answer Types

The list of defined answers that can be utilized in AnswerFactory Application.

There are two main classifications of answers that can be added to a project: extraction answers and query answers. An extraction answer will run GBDX workflows and produce new results over the project's aoi. A query answer will search the current vector database and return existing vectors that both match the query parameters and that intersect the project's aoi. This page goes into more detail about each of the answers available. | Table of Contents | | --- | | [Extraction Answers](#section-extraction-answers) | | [Query Answers](#section-query-answers) | #Extraction Answers# | Answer Name | Answer Description | Recipe Definition | Video | | --- | --- | --- | --- | | Extract Aircrafts | Runs an algorithm over a raster acquisition to identify aircrafts in the image and generate vectors with information on and to notate where the aircrafts are.
