Valle de Tena Dataset |
The data files CERAMIC.TXT and CERAMIC.XLS provide sherd counts by period for each collection lot registered during the Valle de Tena survey. CERAMIC.TXT is a comma delimited ASCII text file; CERAMIC.XLS contains the same data in the form of an Excel spreadsheet. Each line in the ASCII file corresponds to one collection lot. There are 115 lines, each with 9 variables separated by commas. The variables are listed in the following order:
| 1 | Lot ID number. The designated ID number for every collection lot of roughly one hectare or less. When a surface scatter exceeded one hectare, it was subdivided into several collection lots and each was given its own lot number. |
| 2 | Site ID number. Contiguous collection lots were also given a "site" ID number in addition to the individual collection lot numbers that made up the surface scatter. |
| 3 | Lot/Site label. Text strings combining the lot ID number and the site ID number that match the text strings in the GIS dataset (LOTS.DXF, the location of all collection lots). |
| 4 | Collection method: SC=surface collection. In places with good surface visibility, when a sherd scatter was recognized, team members collected every sherd that was encountered within that area, which was designated a collection lot. SP=shovel probe. In places of low or no visibility, shovel probes were carried out at intervals of 100 meters. The contents of positive test pits, then, represent the one-hectare lot they are located in. |
| 5 | Number of sherds from the collection belonging to the Herrera period. |
| 6 | Number of sherds from the collection belonging to the Early Muisca period. |
| 7 | Number of sherds from the collection belonging to the Late Muisca period. |
| 8 | Number of sherds from the collection belonging to the Modern period. |
| 9 | Number of unclassified sherds. |
The first line of the ASCII text file, for example, looks like this:
1,11,1/11,SP,0,0,0,0,2
This means that ceramic materials belong to collection lot 1, site 11, thus the lot/site label is 1/11. The collection method was a shovel probe, which produced 0 Herrera sherds, 0 Early Muisca sherds, 0 Late Muisca sherds, 0 Modern sherds, and 2 unclassified sherds.
The last, or 115 line of the ASCII text file is:
165,91,165/91,SP,4,0,0,0,0
This means that ceramic materials belong to collection lot 165, site 91, thus the lot/site label is 165/91. The collection method was a shovel probe, which produced 4 Herrera sherds, 0 Early Muisca sherds, 0 Late Muisca sherds, 0 Modern sherds, and 0 unclassified sherds.
