enum  FORMATS { DFLT, FULL, COMPACT }
 Keywords for selecting the toString formats. More...
 
enum  MERGE_TYPE { STRICT_MERGE =0, EXPAND_MERGE =1, FULL_MERGE =2, WINDOW_MERGE =3 }
 Available MeteoData merging strategies. When the two stations both have data at a given time step, only the parameters that are not present in station1 will be taken from station2 (ie. station1 has priority). More...
 
enum  MERGE_CONFLICTS { CONFLICTS_PRIORITY_FIRST =0, CONFLICTS_PRIORITY_LAST =1, CONFLICTS_AVERAGE =2 }
 Available MeteoData conflict resolution strategies. When two stations are merged, there is a merge conflict when they have different values for the same parameter at the same timestamp (please note that if one of them has nodata, it is not a conflict: the valid value will be used to replace the nodata). How to handle conflicts is defined by the choice of conflicts resolution strategy. More...

 Simple merge strategy within a vector of MeteoData. All stations that can be considerd as identical (see note) will be merged using the defined conflict resolution policy (see Merge_Conflicts). The priority goes to the stations at the beginning of the vector. For example, if vec[0] has TA but no HS and vec[3] has TA and HS, then vec[0] will keep its TA and get HS from vec[3]. If vec[2] is further away than 5m from vec[0], then it can not contribute to vec[0]. More...

Member Enumeration Documentation

◆ FORMATS

Keywords for selecting the toString formats.

Enumerator
DFLT 

Shows detailed information, skipping nodata fields.

FULL 

Shows detailed information, including nodata fields.

COMPACT 

output optimized to print the content of vector<MeteoData>

◆ MERGE_CONFLICTS

Available MeteoData conflict resolution strategies. When two stations are merged, there is a merge conflict when they have different values for the same parameter at the same timestamp (please note that if one of them has nodata, it is not a conflict: the valid value will be used to replace the nodata). How to handle conflicts is defined by the choice of conflicts resolution strategy.

Enumerator
CONFLICTS_PRIORITY_FIRST 

Station1 has priority over station 2.

CONFLICTS_PRIORITY_LAST 

Station2 has priority over station 1.

CONFLICTS_AVERAGE 

The merged value is the average of station1 and station2.

◆ MERGE_TYPE

Available MeteoData merging strategies. When the two stations both have data at a given time step, only the parameters that are not present in station1 will be taken from station2 (ie. station1 has priority).

Merging strategies for two stations with different sampling rates
Note
Keep in mind that if a station is moving (ie. if its location might change in time) merge strategies other than STRICT_MERGE will introduce potentially invalid metadata (since the new position can not be reconstructed).
Enumerator
STRICT_MERGE 

Station1 receives data from station2 only for common timestamps.

EXPAND_MERGE 

If station2 can provide some data before/after station1, this extra data is added to station1.

FULL_MERGE 

All timestamps from station2 are brought into station1 even if the timestamps don't match.

WINDOW_MERGE 

Similar to a full merge but within the time range of station1.

void mio::MeteoData::merge ( std::vector< MeteoData > &  vec,

If vec[2] is further away than 5m from vec[0], then it can not contribute to vec[0].

Note
two stations are considered to be identical if they fit within a 5m 3D box
the datasets are supposed to contain data at a given time stamp. If the stations don't match a common time stamp, nothing is done

static

Simple merge strategy for vectors containing meteodata for a given timestamp. If some fields of the MeteoData objects given in the first vector are nodata, they will be filled by the matching field from the MeteoData object given in the second argument (if the same location exist).
