CHIP

CHIP surface of a planet. Returned chips contain animage chip and various meta (solar etc) information.

Manage

npm install @totemstan/chip		# install
npm run start [ ? | $ | ...]	# Unit test
npm run verminor				# Roll minor version
npm run vermajor				# Roll major version
npm run redoc					# Regen documentation

Usage

Acquire and optionally configure:

require("@totemstan/chip").config({
	key: value, 						// set key
	"key.key": value, 					// indexed set
	"key.key.": value					// indexed append
}, err =>  {
	console.log( err ? "something evil is lurking" : "look mom - Im running!");
});

where configuration keys follow ENUMS deep copy conventions.

Program Reference

CHIP

Chip surface of spherical objects like the earth.

Requires: module:fs, module:child_process, module:stream, module:enums

• CHIP
  • static
    • .ingestPipe(sql, filter, fileID, src, cb)
    • .ingestList(sql, evs, fileID, cb)
    • .ingestFile(sql, path, fileID, cb)
  • inner
    • ~POS
    • ~AOI

CHIP.ingestPipe(sql, filter, fileID, src, cb)

Pipe src event stream created for this fileID thru the supplied filter(ev,cache) to the evcache db with callback cb(aoi) when finished.

Kind: static method of CHIP

| Param | Type | Description | | --- | --- | --- | | sql | Object | connector | | filter | function | the cache(ev) method supplied to filter(ev,cache) adds an event ev {x,y,z,t,s,class,index,state,fileID} to the evcache db. | | fileID | Number | of internal event store (0 to bypass voxelization) | | src | Stream | source stream created for this fileID | | cb | function | Response callback( ingested aoi info ) |

CHIP.ingestList(sql, evs, fileID, cb)

Ingest events list to internal fileID with callback cb(aoi) when finished.

Kind: static method of CHIP

| Param | Type | Description | | --- | --- | --- | | sql | Object | connector | | evs | Array | events [ ev, ... ] to ingest | | fileID | Number | of internal event store (0 to bypass voxelization) | | cb | function | Response callback( ingested aoi info ) |

CHIP.ingestFile(sql, path, fileID, cb)

Ingest events in evsPath to internal fileID with callback cb(aoi). Ingest events in a file to the internal events file.

Kind: static method of CHIP

| Param | Type | Description | | --- | --- | --- | | sql | Object | connector | | path | String | to events file containing JSON or csv info | | fileID | Number | of internal event store (0 to bypass voxelization) | | cb | function | Response callbatck( ingested aoi info ) |

CHIP~POS

POS Curved earth functions conventions:

t,cols,x,y,lat,gtp[0]
s,rows,y,lon,gtp[1]
old poly = TL,TR,BL,BR,TL
new poly = TL,TR,BR,BL
top = ortho north

Kind: inner class of CHIP

CHIP~AOI

AOI ring = [ [lat,lon], .... ] degs defines aoi chipFeatures = number of feature across chip edge chipPixels = number of pixels across chip edge chipDim = length of chip edge [m] overlap = number of features to overlap chips r = surface radius [km] 6147=earth 0=flat

Kind: inner class of CHIP
