Methods and systems for detection of agricultural spraying errors
A method includes receiving a location sample; determining whether the location sample is sufficient quality; if the location sample is not sufficient quality, discarding the current location sample; if the location sample is sufficient quality, determining whether the location sample is within a same row as a prior location sample; if the location sample is not within the same row as the prior location sample, discarding the location sample; if the location sample is within the same row as the prior location sample, assigning the location sample to the same row and generating an updated block map; determining whether the updated block map includes a potential skipped row; and issuing an alert if the potential skipped row remains a potential skipped row for an amount of time greater than a first threshold.

if the tractor has the further sensor, detecting the activity of the tractor based on the further sensor;
if the tractor does not have the further sensor, determining whether the tractor has an RFID tag;
if the tractor has the RFID tag, determining the tractor activity based on a default activity of the RFID tag; and
if the tractor does not have the RFID tag, determining the tractor activity based on a default activity for the tractor.
4. A method, comprising:
receiving a current location sample;
determining whether the current location sample is of sufficient quality;
if the current location sample is not of sufficient quality, discarding the current location sample;
if the current location sample is of sufficient quality, determining whether the current location sample is within a same row as at least one prior location sample;
if the current location sample is not within the same row as the at least one prior location sample, discarding the current location sample;
if the current location sample is within the same row as the at least one prior location sample, assigning the current location sample to the same row and generating an updated block map;
determining whether the updated block map includes a potential skipped row;
issuing an alert if the potential skipped row remains a potential skipped row for an amount of time greater than a first threshold;
determining whether the updated block map includes potential adjacent skipped rows;
issuing an alert if the potential adjacent skipped rows remain potential adjacent skipped rows for an amount of time greater than a second threshold;
identifying duplicate spraying within a duplicate spraying row; and
issuing an alert for the duplicate spraying.
5. The method of claim 4 , wherein the step of determining whether the current location sample is of sufficient quality comprises comparing a current location sample accuracy to a threshold accuracy, wherein the current location sample is determined to be of sufficient quality if the current location sample accuracy is better than the threshold accuracy, and wherein the current location sample is determined not to be of sufficient quality if the current location sample accuracy is worse than the threshold accuracy.
