DATASET_POINTS
#lines starting with a hash sign are comments, and will be ignored
#fields and values should be separated using tabs, spaces or commas
#use the same separator throughout the file

#color and label for this dataset, which are used in the dataset list box
DATASET_COLOR,#fa9999
DATASET_LABEL,JGI_soil_misc

#radius/size of individual point symbols will be calculated relative to these values
MINIMUM_SIZE,10
MAXIMUM_SIZE,20

#by default, 'size' parameter of each entry is used to calculate the symbol size. You can specify an alternative field,
#which should be present in the optional data
#SIZE_SOURCE,temperature2

#by default, label field (3rd field) will be used for the label display. You can specify an alternative field,
#which should be present in the optional data
#LABEL_SOURCE,temperature

#if CLUSTER_POINTS is set to 1, points which are closer than CLUSTER_DISTANCE pixels are clustered together
CLUSTER_POINTS,0
CLUSTER_DISTANCE,20



#use the following parameters to customize the display of the clustered features. MIN_COUNT and MAX_COUNT define the minimum and maximum number
#of features in a cluster. Based on these numbers, the cluster symbol radius and color will be defined from the RADIUS and COLOR values.
CLUSTER_SYMBOL_MIN_COUNT,1
CLUSTER_SYMBOL_MAX_COUNT,500
CLUSTER_SYMBOL_MIN_RADIUS,10
CLUSTER_SYMBOL_MAX_RADIUS,20

#colors for the cluster symbol label and border
CLUSTER_SYMBOL_BORDER_COLOR,#000000

#transparency of the cluster symbol. 0 is fully opaque, and 100 is fully transparent.

#actual data for individual points follows below the DATA line
#the following fields are available:

#1-2: latitude and longitude: should be in signed degrees format (DDD.dddd)
#  3: label: text label shown on mouseover and in the information popups
#  4: shape: one of the following options: none,circle,poi,bubble,marker,coma,shield,blazon,bookmark,hexagon,diamond,triangle,sign,ban,lozenge,square
#  5: symbol: symbol to render inside the shape (maki or maki2 font symbol name, see https://viglino.github.io/ol-ext/examples/style/map.style.font.html)
#  6: shape color: shape fill color; use RGBA format if transparency is required
#  7: symbol color: symbol color
#  8: relative size: symbol size will be calculated from all relative sizes combined with MINIMUM_SIZE and MAXIMUM_SIZE
# 9-: optional data: any number of additional data entries which are displayed in the information popups. Separate the data label and value with =
#       for example:  temperature=22,description=Some additional text,depth=120
