Description

In order to use the standard hatch legend for Romanian soil texture maps in the ESRI ArcMap-10 electronic format, a dataset consisting a shapefile set (.dbf, .shp, .shx, .sbn, and .sbx files), two different .lyr files, and two different .style files have been prepared (ESRI, 2016). The shapefile set is not a “real” georeferenced layer/coverage; it is designed only to handle all the instants of soil texture items from the standard legend. This legend is related to the current Romanian system of soil taxonomy, SRTS-2012+, and consists of three sub-standards, corresponding to three taxonomic levels: soil qualifiers, soil textural classes, and soil textural subclasses. At the first level there are five hatches for the four soil qualifiers related to soil texture and for the “Skeletic” soil, and two miscellaneous items (various textures and unspecified texture), at the second level there are eight hatches for the seven soil textural classes and for the Skeletic soil, and the two miscellaneous items, and at the third level there are 14 hatches for the 13 soil textural subclasses and for the Skeletic soil, and three miscellaneous items. The correlation with the FAO soil textural classes/subclasses, used by the international soil classification system WRB, is very approximate, given that the Romanian soil classification systems use the Atterberg system to define soil particle size fractions and a specific definition of soil texture classes/subclasses – different from that of FAO. All the standard hatches may be combined to indicate an association of two soil textural classes/sub-classes in a map delineation. Also, the hatch legend may be joined to a color legend for developing a mixed map of soil type and soil texture. The two different .lyr files presented here are: legend_txtcode_srts_en.lyr, and legend_txtcode_en.lyr. Both of them are built using as value field the ‘CODE_TXT3’ field, coding the soil texture subclass at a more detailed level, but the first one uses as labels (explanation texts) the ‘TEXT_RE’ field, storing the soil texture subclass name in SRTS-2012+ and in English language, while the second one, the ‘TEXT_WRB3’ field, storing the SRTS-2012+ soil texture subclass name in English language. In order to exemplify how the legend is displayed, a .jpg file is also presented: legend_txt.jpg, displaying the legend (symbols and labels) according to the first .lyr file. The two different .style files presented here are: txt_codes.style and txt_abbrev.style. The symbol (hatches) for each different map feature has been built and stored in these two .style files, using as name the soil texture subclass code and, respectively, the SRTS-2012+ soil texture subclass name abbreviation.

Files

Steps to reproduce

The presented files may be used to directly implement the Romanian hatch standard in digital soil map legends, or may be adjusted/modified to other specific requirements.
