Working on your NASIS data in conjunction with a standardized OSD component prepared by your SDQS

(4/16/2002 - osd dmu tutorial)

2

The standardized legend and its mapunit table

All names have the -OSDextension

Status is provisional or “correlated” when ready

3

The standardized OSD data has the same structure as other data

Same link to the data mapunit

Mapunit Name, DMU Description,

& Component Nameall have the -osd

extension to make them unique

4

Data Mapunit & Component

DMU and Component names also havethe -OSD extension

5

Selecting a query

You can always query for your

entire legend anda full set of

data mapunits.

6

To load less data while you work, use a query by component that can also download area and correlation

which are needed to run most reports.

Load a component from your survey with this

query.

7

Select target tablesSelect target tables

Select: Data Mapunit, Area, & Correlation(you could select component in

place of dmu)

8

Enter query parameters for your own dmu/component

Area name=your county with standard 2 letter state abbreviation (for your working legend)

Component name = component name

9

Using the same query, enter query parameters for the standardized dmu/component

To query for a standardized OSD DMU:Area Name = osd

Component name has -osd extension

10

These are your selected legends and map units

11

These are your selected data mapunits

12

These are your selected components

13

More than one standardized component?

Sometimes there may be more than one standardizedcomponent developed based on OSD concept

14

Copy and then paste the standardized OSD component into your data mapunit

You will have two components with same name at this time

15

Suggested that you use the standardized component as your base - it’s the “keeper”.

The data in the standardized componenthas been run through NSSH guides

16

Your component will have some data worth keeping

Your component will have interpretive data that you may want to keep. You will want to transfer it to the standardized component

manually, cell copy paste, or copy paste.

17

Your SDQS will provide an MO14 checklist to guide you through the process of verifying and editing the data to

apply it to your survey area

18

Layers and horizons

Some of the earlier standardized horizon table datais done by OSD horizons. Later ones are done as

layers. You want to do layers for your data. Edit as needed.

19

When you are ready, delete your old component and rename the new one

Delete

Rename by dropping the -osd extension

20

Some things about what has and has not been done to the standardized OSD component

21

Most standardized Relative Values (RV) are midpoints. You will need to decide whether to use midpoints, typical pedon values (where appropriate), averages for documented data, or some other value. A team decision for all RVs may be appropriate.

22

Stripped out DMU crop yields.Promoting yields by component

anyway.

23

Slope is range for the series. RV may be midpoint or, if known, slope given for the typical pedon in OSD.

You will edit for this map unit.

24

Kept data that is relatedto the soil. You may needto edit it for your survey.

Deleted any interpretive datathat is phase dependent, such as land

capability class & subclass.

25

Stripped out wildlife data.Phase dependent, but also

no longer supported by NCSS.

26

Calculated classification should be current.If you are correlating a taxadjunct, you will

need to edit the classification and recalculate.

27

Stripped out component crop yields.Phase dependent. Crops differ

from state to state.

28

Left forest and plant data. It is less dependent to phases. You

will need to edit accordingly.

29

Geomorphic Data

Provided basic landscape and landform data.You will need to be more specific if desired.

30

Provided basic three dimensionalmorphometry. Again, you may need to edit

to be more specific.

31

Provided two dimensional morphometryif appropriate for the landform. In this

case, I did not believe it to be appropriate for Flatwoods soil.

32

Provide slope shape in most all cases.You may need to add/edit to be specific

to your component.

33

Parent Material

Provided based on OSD description.

34

Provided flooding frequency and duration as appropriate. Based on

SSSD data.

35

Provided soil moisture status basedon months and depths from old SSSD data.

36

Nothing in the component restrictions ifnot appropriate. None in this case.

37

Complete when appropriate. Probably use TP for RV entries, unless transect data provides

enough data for averages.

38

Provided diagnosticfeatures as appropriate

If series has limitations as far as depth to a diagnostic feature, sometimes used low and high

to show the range. RV is midpoint,averages of data, or from TP.

39

Entered moisture class. This was notpopulated during conversion

and needs to be for interp generation.

40

Stripped out all stored interps and interp restrictions. Hydric soil rating will need to be

kept or added back if component is hydric, and this is where that occurs for now.

41

Hydric soil kind andrestriction added.

42

Added this edit note in Component Textfor osd dmu category

43

Used this edit note to pastea text file of the OSD used.

44

Horizon

Note use of horizon designation column. Some may show “A”, but more recently, have used override to show you what texture

this row applies to. Note that the “Master” column is “A”. Did this for A horizons only. Nomenclature used for

Designation in other layers.

45

Horizon

Did not provide “A” horizon “groups” of textures. If you want a group with your typical texture as RV, use

these rows to bracket all data appropriately and builda group row for your component. I may do some in the future.

46

Sieves developed using the VanLear engine.RVs set at midpoint in most cases.

47

Also used the VanLear engine for:

Atterburgs AASHTO Unified

48

Used other guides from Thunderbook for:Used other guides from Thunderbook for:

Bulk density AWC Ksat for paralithic and lithic horizons

49

Ksat

Data from SSSD has been accepted You need to check the entries to make

sure that fragipans, dense layers, and others limiting layers have correct Ksat data

50

Accepted converted SIR data

LEP

51

Used Dr. Pam Thomas guide

ECEC and CEC according to: mineralogy organic matter Clay %

52

Check to see if OM for “A” horizon agrees with RIC forthe series. I may have applied the range used

in standard horizon data (A horizon-OSD). E, B, and Chorizons all have 0.0-0.25-0.5 entries.

53

If you need to change the organic matterfor your component, make sure you also have

total clay entered, and use these reports to generate a new set of

CEC7 & ECEC datafor your component based on the

appropriate mineralogy.

54

Kw and Kf should be appropriatefor the “A” horizons, but the other layers will need to be edited by you for your RV

texture.

55

If there are rock fragments, make sure that if you change something, that the horizon volume fragments

agree with the >10, 3-10, and #10. “Most” standardized datais rounded to nearest multiple of 5.

56

If you change rock fragment volumes, you will also affect the #40 and #200, and may change the >10 and 3-10 inch.

You may want to run the VanLear engine again based on your rock fragments.

57

Pedon Have not been entering the OSD typical

pedon into NASIS to this point May do in the future, but time is limited Priority is the DMU data Entering your typical pedons for your

own components is more important

58

Limitations of these DMUs No or little interpretive data, such as

yields, capability, hydric limitation, HEL ranking, etc

Did not reference existing lab data. Relied on standard guide sheets. Most of our old SIR data was not related to

lab data anyways (not a true statement for all)

59

Helpful hints

You might want to do the agronomic interpretive data at the end of your project for the full legend so that you consistently apply your state guidelines

Follow the MO14 NASIS checklist to insure that everything is populated appropriately

This includes text notes that you will need to develop per guidelines

60

Helpful hints

If you use a query to load an *-OSD DMU that also loads correlation, deselect the “legend” while you work. Having it in your possession while you work “locks” others out of the legend and does not allow them to create a correlation. When you are ready to do any legend/correlation activities of your own, do a “load related” “correlation” for your DMU. (This hint meant mainly for MO staff)

61

Helpful hints

We are applying the old SIR principle of layers versus horizons. You may need to split layers for your purposes, or even create new layers. This is particularly true if you need to add transition horizons that have a different RIC than the major horizons.

62

Helpful hints

Realize that many surface layers converted from SSSD included “E”, “BE”, or “BA” horizons with the “A” horizon. These horizons have different organic matter content than the A horizon and should now be separated.

63

Helpful hints

Work with your SDQS to insure that appropriate text notes are added. Reference the master MO14 NASIS checklist for text notes that are required or optional and who is responsible for the note.
